Nursing Elites

1. A nurse sees a variety of patients in the community health clinic. Which of the following patients would be at the greatest risk of dehydration?

• A. An 18-year-old basketball player with a stress fracture of the right foot
• B. An infant with diarrhea
• C. A 45-year-old with stomach flu
• D. An elderly patient living alone

Correct answer: B

Rationale: The correct answer is B. Infants are particularly vulnerable to dehydration due to diarrhea because they have a higher fluid turnover and less reserve. Option A, the 18-year-old basketball player with a stress fracture, is less likely to be at the greatest risk of dehydration compared to an infant with diarrhea. Option C, the 45-year-old with stomach flu, may experience dehydration but is not at the same level of risk as an infant with diarrhea. Option D, the elderly patient living alone, could be at risk of dehydration, but infants with diarrhea are at the greatest risk due to their unique physiological characteristics.

2. 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.

3. A nurse develops a plan of care for a client who has a history of hypocalcemia. What interventions should the nurse include in this clients care plan? (Select all that apply.)

• A. Use a draw sheet to reposition the client in bed.
• B. . Strain all urine output and assess for urinary stones.
• C. Provide nonslip footwear for the client to use when out of bed.
• D.

Correct answer: B

Rationale:

4. Your patient has alcoholism, and you may suspect during your assessment that his serum magnesium is low. What will the nurse potentially expect to assess related to hypomagnesemia?

• A. Tremor
• B. Pruritus
• C. Edema
• D. Decreased blood pressure

Correct answer: A

Rationale: The correct answer is A: Tremor. Signs and symptoms of hypomagnesemia primarily affect the neuromuscular system and can include tremors, confusion, tetany, laryngeal stridor, and ataxia. Pruritus (choice B) refers to itching and is not typically associated with hypomagnesemia. Edema (choice C) is swelling caused by fluid retention and is not a common manifestation of hypomagnesemia. Decreased blood pressure (choice D) is not a typical sign of hypomagnesemia; instead, low magnesium levels are more likely to cause hypertension.

5. . A nurse assesses a client who had an intraosseous catheter placed in the left leg. Which assessment finding is of greatest concern?

• A. The catheter has been in place for 20 hours.
• B. . The client has poor vascular access in the upper extremities.
• C. The catheter is placed in the proximal tibia.
• D. The clients left lower extremity is cool to the touch.

Correct answer: D
