Nursing Elites

1. Which electrolyte imbalance is a potential side effect of diuretics?

• A. Hyperkalemia
• B. Hypercalcemia
• C. Hypomagnesemia
• D. Hypokalemia

Correct answer: D

Rationale: The correct answer is D, Hypokalemia. Diuretics commonly cause hypokalemia due to increased urinary excretion of potassium. Hyperkalemia (Choice A) is the opposite, characterized by high potassium levels and is not typically associated with diuretics. Hypercalcemia (Choice B) is an elevated calcium level, which is not a common side effect of diuretics. Hypomagnesemia (Choice C) is low magnesium levels, which can be a side effect of diuretics, but the most common electrolyte imbalance associated with diuretics is hypokalemia.

2. The HCP orders cultures of the urethral urine, bladder urine, and prostatic fluid. Which instructions would the nurse teach to achieve the first two (2) specimens?

• A. Collect the first 15 mL in one jar and then the next 50 mL in another
• B. Collect three (3) early morning, clean voided urine specimens
• C. Collect the specimens after the HCP massages the prostate
• D. Collect a routine urine specimen for analysis

Correct answer: A

Rationale: To obtain accurate cultures of urethral and bladder urine, the nurse should instruct the patient to collect the first 15 mL of urine in one container and the subsequent 50 mL in another. This method ensures that the specimens are separated appropriately for analysis. Choices B, C, and D are incorrect because collecting three early morning urine specimens, massaging the prostate, or collecting a routine urine specimen would not provide the specific separation of urethral and bladder urine required for this particular test.

3. Which vitamin deficiency is commonly associated with prolonged antibiotic use?

• A. Vitamin A
• B. Vitamin B6
• C. Vitamin C
• D. Vitamin K

Correct answer: D

Rationale: The correct answer is Vitamin K. Prolonged antibiotic use can disrupt the gut flora, leading to Vitamin K deficiency and an increased risk of bleeding. Vitamin A deficiency is not commonly associated with antibiotic use. Similarly, Vitamin B6 and Vitamin C deficiencies are not typically linked to prolonged antibiotic use.

4. The type of lipoprotein that carries cholesterol from tissues to the liver for excretion is:

• A. Very low-density lipoprotein
• B. Intermediate-density lipoprotein
• C. Low-density lipoprotein
• D. High-density lipoprotein

Correct answer: D

Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as the 'good' cholesterol and plays a crucial role in transporting cholesterol from tissues back to the liver for excretion. This process helps in reducing the buildup of cholesterol in the bloodstream, thus lowering the risk of heart diseases. Very low-density lipoprotein (Option A), Intermediate-density lipoprotein (Option B), and Low-density lipoprotein (Option C) are not responsible for carrying cholesterol back to the liver for excretion like HDL does. Instead, they are associated with different functions related to cholesterol transportation within the body.

5. The nurse is aware that norepinephrine is secreted by which endocrine gland?

• A. The pancreas
• B. The adrenal cortex
• C. The adrenal medulla
• D. The anterior pituitary gland

Correct answer: C

Rationale: The correct answer is C: The adrenal medulla. Norepinephrine is secreted by the adrenal medulla and is involved in the body's 'fight or flight' response. The pancreas (choice A) secretes insulin and glucagon, not norepinephrine. The adrenal cortex (choice B) secretes hormones like cortisol and aldosterone, but not norepinephrine. The anterior pituitary gland (choice D) secretes various hormones like growth hormone and thyroid-stimulating hormone, but not norepinephrine.
