1. A client has been prescribed vasopressin for the treatment of diabetes insipidus. What is the expected pharmacological action of this medication?
- A. To stimulate the pancreas to secrete insulin
- B. To slow the absorption of glucose in the intestine
- C. To increase reabsorption of water in the renal tubules
- D. To increase blood pressure
Correct answer: C
Rationale: The correct answer is C: To increase reabsorption of water in the renal tubules. Vasopressin mimics the action of antidiuretic hormone (ADH) by increasing the reabsorption of water in the renal tubules. This leads to decreased urine output, helping to manage symptoms of diabetes insipidus, which is characterized by excessive thirst and urination. Choices A, B, and D are incorrect. Vasopressin does not stimulate the pancreas to secrete insulin, slow the absorption of glucose in the intestine, or directly increase blood pressure.
2. Which of the following would increase a client's risk of ovarian cancer?
- A. History of fibroids
- B. Early menopause
- C. Endometriosis
- D. Polycystic ovary syndrome
Correct answer: C
Rationale: The correct answer is C, Endometriosis. Endometriosis is associated with an increased risk of developing ovarian cancer due to chronic inflammation and hormonal imbalances. The exact cause is not fully understood, but women with endometriosis should be monitored closely. Choices A, B, and D are incorrect as they are not directly linked to an increased risk of ovarian cancer. Fibroids, early menopause, and polycystic ovary syndrome do not have a known direct correlation with ovarian cancer risk.
3. Which of the following interventions is most appropriate for a client with hyperemesis gravidarum?
- A. Encourage high-calorie meals
- B. Administer intravenous fluids
- C. Provide frequent small meals
- D. Limit fluid intake
Correct answer: B
Rationale: The correct answer is B: Administer intravenous fluids. Hyperemesis gravidarum is severe, persistent nausea and vomiting during pregnancy that can lead to dehydration and electrolyte imbalances. The priority intervention is to administer intravenous fluids to maintain hydration. Encouraging high-calorie meals (Choice A) may exacerbate symptoms due to increased gastric stimulation. Providing frequent small meals (Choice C) may not be effective in severe cases where continuous vomiting occurs. Limiting fluid intake (Choice D) is contraindicated in hyperemesis gravidarum as dehydration is a significant concern.
4. Four clients present to the emergency department. The nurse should plan to see which of the following clients first?
- A. A 6-year-old client with a dislocated shoulder
- B. A 26-year-old client with sickle cell disease and severe joint pain
- C. A 76-year-old client who is confused, febrile, and has foul-smelling urine
- D. A 50-year-old client who has slurred speech and reports a headache
Correct answer: D
Rationale: The correct answer is D. The client with slurred speech and a headache may be experiencing a stroke, which is a medical emergency that requires immediate attention to prevent irreversible brain damage. While each client requires prompt assessment and care, the priority is to address potentially life-threatening conditions first. Choices A, B, and C, although important, do not present with symptoms as critical as those of a possible stroke, which necessitates urgent intervention.
5. A nurse is preparing to administer prochlorperazine 2.5 mg IV. Available is prochlorperazine injection 5 mg/mL. How many mL should the nurse administer?
- A. 0.2 mL
- B. 0.5 mL
- C. 1.0 mL
- D. 1.5 mL
Correct answer: B
Rationale: To determine the volume of prochlorperazine to administer, divide the prescribed dose (2.5 mg) by the concentration of the medication (5 mg/mL). This calculation results in 0.5 mL. Therefore, the nurse should administer 0.5 mL to deliver the correct dose. Choice A (0.2 mL) is incorrect as it miscalculates the dosage. Choices C (1.0 mL) and D (1.5 mL) are also incorrect as they do not accurately reflect the calculated volume needed for the dose.
