A patient with diabetes insipidus is prescribed desmopressin. What is the primary purpose of this medication?
- A. Increase urine output
- B. Reduce blood sugar levels
- C. Decrease urine output
- D. Lower blood pressure
Correct Answer: C
Rationale: Desmopressin is a synthetic form of vasopressin used to replace the hormone in diabetes insipidus. The primary purpose is to decrease urine output by increasing water reabsorption in the kidneys, thereby reducing excessive urination and preventing dehydration. Choice A is incorrect as desmopressin actually decreases urine output. Choice B is incorrect as desmopressin does not directly affect blood sugar levels. Choice D is incorrect as desmopressin does not primarily lower blood pressure.

A patient with epilepsy is prescribed phenytoin. What is the primary side effect the nurse should monitor for?
- A. Hypotension
- B. Gingival hyperplasia
- C. Bradycardia
- D. Hyperkalemia
Correct Answer: B
Rationale: The correct answer is B: Gingival hyperplasia. Phenytoin is known to cause gingival overgrowth as a side effect. This is due to its effect on fibroblasts in the gums, leading to increased connective tissue production. Hypotension (A), bradycardia (C), and hyperkalemia (D) are not common side effects of phenytoin. Monitoring for gingival hyperplasia is crucial to prevent complications such as difficulty in eating, speaking, and maintaining oral hygiene.
When should the charge nurse intervene based on the observed behavior?
- A. Two staff members are overheard talking about a cure for AIDS outside a client's room.
- B. A hospital transporter is reading a client's history and physical while waiting for an elevator.
- C. A UAP tells a client, 'It's hard to quit drinking but Alcoholics Anonymous helped me.'
- D. Two visitors are discussing a hospitalized client's history of drug abuse in the visitor's lounge.
Correct Answer: B
Rationale: The correct answer is B because it violates patient confidentiality. Reading a client's history and physical in a public area breaches the client's privacy rights. The other choices do not directly compromise patient confidentiality. A involves discussing a cure for AIDS, which is not a breach of confidentiality. C involves sharing personal experiences with the client, and D involves discussing a client's history of drug abuse in a visitor's lounge, which may not be overheard by the client or staff directly involved in the client's care.
A patient with rheumatoid arthritis is taking prednisone. What is an important side effect for the nurse to monitor?
- A. Hyperglycemia
- B. Bradycardia
- C. Hypotension
- D. Hyperkalemia
Correct Answer: A
Rationale: The correct answer is A: Hyperglycemia. Prednisone is a corticosteroid that can cause an increase in blood glucose levels by promoting gluconeogenesis and decreasing insulin sensitivity. Monitoring for hyperglycemia is crucial as it can lead to serious complications such as diabetic ketoacidosis. Bradycardia (B) and hypotension (C) are not typical side effects of prednisone, as it tends to cause fluid retention and hypertension. Hyperkalemia (D) is also unlikely as prednisone can actually cause hypokalemia due to increased renal potassium excretion.
A patient with rheumatoid arthritis is prescribed methotrexate. What is an important teaching point for the nurse to provide?
- A. Take folic acid supplements as prescribed.
- B. Avoid alcohol completely.
- C. Expect to see immediate results.
- D. Limit fluid intake to 1 liter per day.
Correct Answer: A
Rationale: The correct answer is A: Take folic acid supplements as prescribed. Methotrexate can lead to folic acid deficiency, causing side effects. Supplementing with folic acid can help manage these side effects. It is crucial for the nurse to emphasize the importance of taking folic acid as prescribed to prevent adverse effects.
Summary of Incorrect Choices:
B: Avoid alcohol completely - While alcohol should be limited or avoided due to potential liver toxicity with methotrexate, complete avoidance may not be necessary for all patients.
C: Expect to see immediate results - Methotrexate takes time to work, and patients should not expect immediate results. Patience is necessary.
D: Limit fluid intake to 1 liter per day - There is no specific guideline to limit fluid intake with methotrexate. Adequate hydration is important for overall health.
A client with chronic obstructive pulmonary disease (COPD) is receiving prednisone (Deltasone). Which side effect should the nurse monitor for?
- A. Hypoglycemia
- B. Infection
- C. Hypotension
- D. Weight loss
Correct Answer: B
Rationale: The correct answer is B: Infection. Prednisone is a corticosteroid that suppresses the immune system, increasing the risk of infections in patients. The nurse should monitor for signs of infection such as fever, increased white blood cell count, and localized symptoms.
Rationale:
A: Hypoglycemia is not a common side effect of prednisone. Prednisone typically causes hyperglycemia.
C: Hypotension is not a common side effect of prednisone. Prednisone can actually cause fluid retention and increased blood pressure.
D: Weight loss is not a common side effect of prednisone. Prednisone can actually cause weight gain due to fluid retention and increased appetite.
