B) Check the client's apical pulse. C) Notify the healthcare provider. D) Repeat the serum potassium level. - The nurse should first withhold the scheduled dose of Cozaar (A) because the client is hyperkalemic (normal range 3.5 to 5 mEq/L). Although hypokalemia is usually associated with diuretic therapy in heart failure, hyperkalemia is associated with several heart failure medications, including ARBs. Because hyperkalemia may lead to cardiac dysrhythmias, the nurse should check the apical pulse for rate and rhythm (B), and the blood pressure. Before repeating the serum study (D), the nurse should notify the healthcare provider (C) of the findings. Taking hydromorphone (Dilaudid) PO q4h at home. Following surgery Dilaudid IV q4h PRN and butorphanol tartrate (Stadol) IV q4h PRN are prescribed for pain.

What assessment has the highest priority before initiating the PCA pump? A) The expiration date on the morphine syringe in the pump. B) The rate and depth of the client's respirations. C) The type of anesthesia used during the surgical procedure. D) The client's subjective and objective signs of pain. - A life-threatening side effect of intravenous administration of morphine sulfate, an opiate narcotic, is respiratory depression (B). The PCA pump should be stopped and the healthcare provider notified if the client's respiratory rate falls below 12 breaths per minute, and the nurse should anticipate adjustments in the client's dosage before the PCA pump is restarted. (A, C, and D) provide helpful information, but are not as high a priority as the assessment described in (B). A peak and trough level must be drawn for a client receiving antibiotic therapy Immediately before the next antibiotic dose is given When assessing an adolescent who recently overdosed on acetaminophen (Tylenol), it is most important for the nurse to assess for pain in which area of the body Abdomen - Acetaminophen toxicity can result in liver damage; therefore, it is especially important for the nurse to assess for pain in the right upper quadrant of the abdomen (B), which might indicate liver damage. (A, C, and D) are not areas where pain would be anticipated.

Which antidiarrheal agent should be used with caution in clients taking high dosages of aspirin for arthritis Bismuth subsalicylate (Pepto Bismol) - Bismuth subsalicylate (Pepto Bismol) contains a subsalicylate that increases the potential for salicylate toxicity when used concurrently with aspirin (acetylsalicylic acid, another salicylate preparation). (A, B, and D) do not pose the degree of risk of drug interaction with aspirin as Pepto Bismol would. Prescriptions for morphine sulphate 2.5 mg IV q6h and ketorolac (Toradol) 30 mg IV q6h administer both medications according to the prescription - An adult client has prescriptions for morphine sulfate 2.5 mg IV q6h and ketorolac (Toradol) 30 mg IV q6h. Which action should the nurse implement? A) Administer both medications according to the prescription. B) Hold the ketorolac to prevent an antagonistic effect. C) Hold the morphine to prevent an additive drug interaction. D) Contact the healthcare provider to clarify the prescription. - Morphine and ketorolac (Toradol) can be administered concurrently (A), and may produce an additive analgesic effect, resulting in the ability to reduce the dose of morphine, as seen in this prescription. Toradol is an antiinflammatory analgesic, and does not have an antagonistic effect with morphine (B), like an agonist-antagonist medication would have. An additive analgesic effect is desirable (C), because it allows a reduced dose of morphine. This prescription does not require any clarification, and can be administered safely as written (D). Hyperlipidemia receives a prescription for niacin (Niaspan) Expected duration of flushing - A client with hyperlipidemia receives a prescription for niacin (Niaspan). Which client teaching is most important for the nurse to provide? A) Expected duration of flushing. B) Symptoms of hyperglycemia. C) Diets that minimize GI irritation.

Morphine sulphate (A) is an opioid analgesic used in oncology to manage severe or intractable pain. Ibuprofen (B), a nonsteroidal antiinflammatory drug (NSAID), provides relief for mild to moderate pain, suppression of inflammation, and reduction of fever. Amitriptyline (C), a tricyclic antidepressant, is often prescribed for pain related to neuropathic origin and provides a reduction in opioid dosage. Upon admission to the emergency center, an adult client with acute status asthmaticus is prescribed this series of medications In which order Albuterol (Proventil) puffs Salmeterol (Serevent Diskus) Prednisone (Deltasone) orally Gentamicin (Garamycinim) IM - Status asthmaticus is potentially a life-threatening respiratory event, so albuterol (C), a beta2 adrenergic agonist and bronchodilator, should be administered by inhalation first to provide rapid and deep topical penetration to relieve bronchospasms, dilate the bronchioles, and increase oxygenation. In stepwise management of persistent asthma, a long-action bronchodilator, such as salmeterol (Serevent Diskus) (D) with a 12-hour duration of action should be given next. Prednisone (A), an oral corticosteroid, provides prolonged anti-inflammatory effects and should be given after the client's respiratory distress begins to resolves. Gentamicin (B), an antibiotic, is given deep IM, which can be painful, and may require repositioning the client, so should be last in the sequence. 43- year-old female receiving thyroid replacement hormone following a thyroidectomy What adverse effects associated with thyroid hormone toxicity should the nurse instruct the client to report promptly to the healthcare provider? Tachycardia and chest pain - Thyroid replacement hormone increases the metabolic rate of all tissues, so common signs and symptoms of toxicity include tachycardia and chest pain (B). (A, C, and D) do not indicate a thyroid hormone toxicity.

Which statement reflects the correct drug-specific teaching the nurse should provide to this client? A) Increase consumption of potassium-rich foods since low potassium levels can cause muscle spasms. B) Have serum electrolytes checked at the next scheduled appointment to assess hyponatremia, a cause of cramping. C) Make an appointment to see the healthcare provider, because muscle pain may be an indication of a serious side effect. D) Be sure to consume a low-cholesterol diet while taking the drug to enhance the effectiveness of the drug. - Myopathy, suggested by the leg pain and weakness, is a serious, and potentially life-threatening, complication of Lipitor, and should be evaluated immediately by the healthcare provider (C). Although electrolyte imbalances such as (A or B) can cause muscle spasms in some cases, this is not the likely cause of leg pain in the client receiving Lipitor, and evaluation by the healthcare provider should not be delayed for any reason. A low-cholesterol diet is recommended for those taking Lipitor since the drug is used to lower total cholesterol (D), but diet is not related to the leg pain symptom. The healthcare provider prescribes naproxen (Naproxen) twice daily for a client with osteoarthritis of the hands Another type of non- steroidal anti-inflammatory drug may be indicated - The healthcare provider prescribes naproxen (Naproxen) twice daily for a client with osteoarthritis of the hands.

C) Administer the 60 mg dose of Imdur and a PRN dose of acetaminophen (Tylenol). D) Do not administer the next dose of Imdur or any acetaminophen until notifying the healthcare provider. - Imdur is a nitrate which causes vasodilation. This vasodilation can result in headaches, which can generally be controlled with acetaminophen (C) until the client develops a tolerance to this adverse effect. (A and B) may result in the onset of angina if a therapeutic level of Imdur is not maintained. Lying down (D) is less likely to reduce the headache than is a mild analgesic. Coronary artery Dz. is taking digoxin (Lanoxin) receives a new prescription for atorvastatin (Lipitor) Vomiting - A client with coronary artery disease who is taking digoxin (Lanoxin) receives a new prescription for atorvastatin (Lipitor). Two weeks after initiation of the Lipitor prescription, the nurse assesses the client. Which finding requires the most immediate intervention? A) Heartburn. B) Headache. C) Constipation. D) Vomiting. - Vomiting, anorexia and abdominal pain are early indications of digitalis toxicity.
