1. A postoperative patient who had surgery for a perforated gastric ulcer has been receiving nasogastric suction for 3 days. The patient now has a serum sodium level of 127 mEq/L (127 mmol/L). Which prescribed therapy should the nurse question?
- A. Infuse 5% dextrose in water at 125 mL/hr.
- B. Administer IV morphine sulfate 4 mg every 2 hours PRN.
- C. Give IV metoclopramide (Reglan) 10 mg every 6 hours PRN for nausea.
- D. Administer 3% saline if serum sodium decreases to less than 128 mEq/L.
Correct answer: A
Rationale: The nurse should question the prescription to infuse 5% dextrose in water at 125 mL/hr because the patient's gastric suction has been depleting electrolytes, leading to hyponatremia. Therefore, the IV solution should include electrolyte replacement. Solutions like lactated Ringer’s solution would usually be ordered. The other choices (B, C, and D) are appropriate for a postoperative patient with gastric suction, addressing pain management, nausea control, and correcting hyponatremia if it drops below a certain level.
2. A client is admitted to the postpartum unit and tells the nurse she had rheumatic fever as a child, which resulted in some 'heart damage'. The nurse knows that this client is at particular risk for developing heart failure during the immediate postpartum period. Based on the client's history, which nursing problem has the highest priority?
- A. Nausea and vomiting.
- B. Risk for infection.
- C. Sleep deprivation.
- D. Fluid volume excess.
Correct answer: D
Rationale: Fluid volume excess is a priority concern in this client, as heart damage from rheumatic fever can impair the heart's ability to manage increased blood volume postpartum, leading to potential heart failure. Monitoring and managing fluid volume status are crucial to prevent complications in this high-risk client. Choices A, B, and C are not the highest priority in this situation. Nausea and vomiting, risk for infection, and sleep deprivation are important but do not pose an immediate threat to the client's physiologic stability compared to the risk of heart failure due to fluid volume excess.
3. The client has been managing angina episodes with nitroglycerin. Which of the following indicates the drug is effective?
- A. Decreased chest pain.
- B. Increased blood pressure.
- C. Decreased blood pressure.
- D. Decreased heart rate.
Correct answer: A
Rationale: The correct answer is A: Decreased chest pain. Nitroglycerin is a vasodilator that works by decreasing myocardial oxygen consumption, which helps to reduce chest pain caused by angina. Therefore, a reduction in chest pain is a positive indicator of the drug's effectiveness. Choices B, C, and D are incorrect because nitroglycerin does not typically increase blood pressure or heart rate; instead, it often causes a decrease in blood pressure due to vasodilation and may cause a reflex tachycardia (increased heart rate) as a compensatory response to lowered blood pressure.
4. After a lumbar puncture, a client reports a severe headache. What is the nurse's priority intervention?
- A. Administer a dose of acetaminophen.
- B. Elevate the head of the bed.
- C. Encourage the client to rest in a dark room.
- D. Administer caffeine to relieve the headache.
Correct answer: B
Rationale: After a lumbar puncture, a severe headache is often caused by cerebrospinal fluid leakage. Elevating the head of the bed or having the client lie flat can reduce cerebrospinal fluid pressure and alleviate the headache. These positions help prevent further fluid loss and relieve discomfort. While acetaminophen or caffeine may help in relieving the headache, changing the client's position is the priority to address the underlying cause. Resting in a dark room may be beneficial for headache relief but is not the priority intervention compared to adjusting the position to manage cerebrospinal fluid pressure.
5. While teaching a group of adults about health promotion activities, a nurse identifies a behavior that poses the most significant risk factor for the development of skin cancer. Which behavior should the nurse address?
- A. Consuming a high-fat diet
- B. Using tanning beds
- C. Smoking cigarettes
- D. Drinking alcohol
Correct answer: B
Rationale: Using tanning beds is the most significant risk factor for developing skin cancer. Ultraviolet (UV) radiation from tanning beds damages the skin and increases the risk of skin cancer. Consuming a high-fat diet, smoking cigarettes, and drinking alcohol are unhealthy behaviors but are not directly linked to the development of skin cancer like UV exposure from tanning beds.
