Question 1 of 5
The nurse teaches a patient taking amphotericin B to report which signs and symptoms to the health care provider?
Correct Answer: C
Rationale: Amphotericin B is an antifungal medication that can cause nephrotoxicity, leading to decreased urine output and renal impairment. Patients should be instructed to report any changes in urinary output promptly. Changes in sight and hearing are not typical adverse effects of amphotericin B. A painful red rash and blisters may indicate an allergic reaction but are less common than nephrotoxicity.
Question 2 of 5
A patient was prescribed sertraline (Zoloft) for the treatment of depression and anxiety. The patient's spouse calls the clinic and reports the patient is increasingly moody and seems 'disconnected with life.' What is the best response by the nurse?
Correct Answer: B
Rationale: Worsening mood and disconnection on sertraline signal risk-e.g., suicidal ideation, per SSRI warnings-needing urgent clinic assessment. Benadryl is inappropriate-sedation won't fix. Holding meds risks withdrawal. Doubling dose escalates danger. Immediate evaluation ensures safety, per protocol.
Question 3 of 5
A patient about to receive a morning dose of digoxin has an apical pulse of 53 beats/min. What will the nurse do next?
Correct Answer: D
Rationale: The correct action is to check the radial pulse for 1 full minute. When administering digoxin, it is important to assess the apical pulse before giving the medication. A heart rate of 53 beats/min is below the normal range, especially for a patient taking digoxin, which can slow heart rate further. The nurse should check the radial pulse for a full minute to verify the heart rate accurately and assess for any abnormalities. This step is crucial to ensure patient safety and prevent potential complications associated with bradycardia. In this situation, it is necessary to withhold the dose and notify the prescriber to determine the appropriate course of action based on the assessment findings.
Question 4 of 5
A 25-year-old male comes to the emergency department with crushing, substernal chest pain. The pain radiates up to his jaw and down to his right arm. He has never had chest pain like this before. An ECG shows ST elevations in leads I, II, and AVF. A detailed history reveals that he had used cocaine 2 h prior to the onset of chest pain. Which of the following medications is contraindicated in the treatment of myocardial infarction caused by his cocaine use?
Correct Answer: C
Rationale: Cocaine-induced MI (ST elevations) contraindicates β-blockers . They exacerbate coronary vasospasm via unopposed α-stimulation. ACE inhibitors , aspirin , calcium channel blockers , and nitroglycerin (E) are safe. β-Blockers worsen this unique MI etiology.
Question 5 of 5
The nurse is aware that efficient absorption of calcium is assisted by
Correct Answer: D
Rationale: Calcium absorption in the small intestine relies heavily on vitamin D, which enhances the process by increasing the expression of calcium-binding proteins and improving gut uptake efficiency. Without adequate vitamin D, calcium absorption drops significantly, leading to potential bone health issues like osteoporosis or osteomalacia. Intrinsic factor, produced in the stomach, is critical for vitamin B12 absorption, not calcium, as it binds B12 for uptake in the ileum. Coenzymes, while involved in metabolic reactions, don't directly facilitate calcium absorption; their role is broader and unrelated to this specific process. Phosphorus, an abundant mineral, works with calcium in bone formation but doesn't enhance its absorption-in fact, excessive phosphorus can compete with calcium. Vitamin D's active form, calcitriol, regulates calcium levels by promoting its transport across intestinal cells, making it indispensable for maintaining skeletal integrity. This mechanism underscores why vitamin D deficiency impairs calcium utilization, distinguishing it from the other options, which lack a direct link to absorption efficiency.
