Question 1 of 5
Which of the following drugs is more likely to cause hyperkalaemia than hypokalaemia in a patient with diabetes and estimated glomerular filtration rate (eGFR) within the 'normal' reference range?
Correct Answer: D
Rationale: Hyperkalemia involves elevated potassium, hypokalemia reduced levels. Amphotericin causes hypokalemia via renal potassium wasting, not hyperkalemia. Prednisolone, a glucocorticoid, promotes potassium excretion, risking hypokalemia. Low molecular weight heparin (LMWH) rarely affects potassium directly with normal eGFR. Salmeterol, a beta-agonist, can shift potassium intracellularly, causing hypokalemia. Insulin, in diabetes management, drives potassium into cells with glucose, potentially causing hyperkalemia if renal excretion is impaired, though less common with normal eGFR. However, its potassium-shifting effect makes hyperkalemia more likely than hypokalemia compared to others, especially in acute settings, a key consideration in diabetic care.
Question 2 of 5
A male client has erectile dysfunction. Which systems should be assessed that could contribute to the erectile dysfunction?
Correct Answer: A
Rationale: Erectile dysfunction (ED) often stems from cardiovascular issues, like atherosclerosis or hypertension, which impair blood flow to the penis, a vascular process essential for erection. The integumentary system, while relevant to skin health, doesn't directly influence ED unless severe conditions affect genital tissue, which is rare. Endocrine disorders, such as diabetes or low testosterone, disrupt hormonal balance critical for libido and erectile function, making it a key area. The nervous system, including spinal cord injuries or neuropathy, affects nerve signals for arousal, another vital component. Cardiovascular assessment is prioritized because ED can signal underlying heart disease, with shared risk factors like smoking or high cholesterol, and its vascular basis often precedes overt cardiac symptoms, necessitating a thorough check of circulation and heart health to pinpoint or rule out this common cause.
Question 3 of 5
The patient is complaining of a severe headache. The physician orders aspirin. Which action by the nurse will result in the fastest relief of the patient's headache?
Correct Answer: D
Rationale: Aspirin on an empty stomach absorbs fastest, speeding headache relief by avoiding food delays-fatty meals like peanut butter slow gastric emptying, reducing onset. Alkaline foods may alter pH but don't hasten absorption significantly. Enteric-coated forms delay release for GI protection, not speed. Empty stomach delivery maximizes bioavailability quickly, aligning with pain relief urgency.
