1. What electrolyte value should be monitored when a patient is receiving a loop diuretic?

A. Calcium levels
B. Phosphorus levels
C. Potassium levels
D. Magnesium levels

Correct answer: C

Rationale: When a patient is receiving a loop diuretic like furosemide (Lasix), potassium levels should be monitored closely. Loop diuretics act on the ascending loop of Henle to inhibit the reabsorption of sodium and water, leading to potassium loss. Monitoring potassium levels is crucial to prevent hypokalemia, which can result in serious complications such as cardiac arrhythmias. Calcium levels (Choice A), phosphorus levels (Choice B), and magnesium levels (Choice D) are not typically affected directly by loop diuretics and do not require routine monitoring in this context.

2. The ICU nurse is caring for a patient who experienced trauma in a workplace accident. The patient is complaining of having trouble breathing with abdominal pain. An ABG reveals the following results: pH 7.28, PaCO2 50 mm Hg, HCO3 23 mEq/L. The nurse should recognize the likelihood of what acidbase disorder?

A. Respiratory acidosis
B. Metabolic alkalosis
C. Respiratory alkalosis
D. Mixed acidbase disorder

Correct answer: D

Rationale:

3. A nurse teaches a client who is being discharged home with a peripherally inserted central catheter (PICC). Which statement should the nurse include in this clients teaching?

A. avoid carrying your grandchild with the arm that has the central catheter.
B. Be sure to place the arm with the central catheter in a sling during the day
C. Flush the peripherally inserted central catheter line with normal saline daily.
D. You can use the arm with the central catheter for most activities of daily living.

Correct answer: A

Rationale:

4. After providing discharge teaching, a nurse assesses the clients understanding regarding increased risk for metabolic alkalosis. Which statement indicates the client needs additional teaching?

A. . I dont drink milk because it gives me gas and diarrhea
B. I have been taking digoxin every day for the last 15 years
C. . I take sodium bicarbonate after every meal to prevent heartburn
D. In hot weather, I sweat so much that I drink six glasses of water each day.

Correct answer: C

Rationale:

5. Who would have the greatest percentage of body water?

A. an obese male
B. a nonobese male
C. a nonobese female
D. a newborn

Correct answer: D

Rationale: Newborns have a higher percentage of body water compared to adults due to their higher body fluid content. Factors such as the higher ratio of body surface area to body volume and lower body fat content contribute to this. This is why a newborn would have the greatest percentage of body water. Choices A, B, and C are incorrect because obesity and gender do not determine the percentage of body water in individuals. Therefore, the correct answer is a newborn.
