1. 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.

2. After teaching a client who was malnourished and is being discharged, a nurse assesses the clients understanding. Which statement indicates the client correctly understood teaching to decrease risk for the development of metabolic acidosis?

• A. I will drink at least three glasses of milk each day.
• B. . I will eat three well-balanced meals and a snack daily.
• C. . I will not take pain medication and antihistamines together.
• D. I will avoid salting my food when cooking or during meals.

Correct answer: A

3. A patient's lab results show a slight decrease in potassium. The physician has declined to treat with drug therapy but has suggested increasing the potassium through diet. Which of the following would be a good source of potassium?

• A. Apples
• B. Asparagus
• C. Carrots
• D. Bananas

Correct answer: D

Rationale: Bananas are an excellent source of potassium, making them a good choice to increase potassium levels through diet. While apples, asparagus, and carrots are nutritious, they are not particularly high in potassium compared to bananas. Therefore, choosing bananas would be more effective in increasing the patient's potassium intake.

4. A nurse is taking care of a 65-year-old female patient in a medical-surgical unit who is in renal failure; during the assessment, the patient complains of tingling in her lips and fingers. When the nurse takes her blood pressure, she has a spasm in her wrist and hand. The nurse suspects:

• A. Hypophosphatemia
• B. Hypocalcemia
• C. Hypermagnesemia
• D. Hyperkalemia

Correct answer: B

Rationale: The patient's symptoms of tingling in the lips and fingers along with the wrist and hand spasm are indicative of tetany, a characteristic manifestation of hypocalcemia. Hypocalcemia and hypomagnesemia can present with sensations of tingling in the extremities and around the mouth. The spasm in the wrist and hand when taking blood pressure could be due to slight ischemia of the ulnar nerve, further supporting the suspicion of hypocalcemia in this patient. Hypophosphatemia, hypermagnesemia, and hyperkalemia do not typically present with these specific symptoms and manifestations.

5. 1.A nurse prepares to insert a peripheral venous catheter in an older adult client. Which action should the nurse take to protect the clients skin during this procedure?

• A. Lower the extremity below the level of the heart.
• B. Apply warm compresses to the extremity.
