The nurse is caring for a client with decreased cardiac output secondary to heart failure with fluid volume overload. The effects of diminished renal perfusion will have which physiologic response?
- A. Diuresis
- B. Increased fluid retention
- C. Elevated bicarbonate level
- D. Paroxysmal idiopathic narcosis
Correct Answer: B
Rationale: When there is diminished renal perfusion due to decreased cardiac output, the kidneys receive less blood flow. This leads to a decrease in urine output and an increase in fluid retention, as the kidneys are not able to effectively filter and excrete excess fluid. Elevated bicarbonate level and paroxysmal idiopathic narcosis are not typically associated with diminished renal perfusion in heart failure. Therefore, the correct answer is 'Increased fluid retention.'

The nurse is caring for a client with full-thickness burns to the left arm and trunk. What is the priority for this client?
- A. Pain management
- B. Airway assessment
- C. Fluid volume status monitoring
- D. Risk for infection prevention
Correct Answer: C
Rationale: Correct! With full-thickness burns, there is a significant risk of fluid loss through the burn wound and fluid shift, leading to hypovolemia and shock. Monitoring and maintaining the client's fluid volume status is crucial to prevent complications like hypovolemic shock. Pain management (Option A) is essential but not the priority in this situation. While airway assessment (Option B) is crucial, it is typically assessed first in clients with respiratory distress. Preventing infection (Option D) is important but managing fluid volume status takes precedence in the initial care of a client with full-thickness burns.
The nurse is teaching a community health class for cancer prevention and screening. Which individual has the highest risk for colon cancer?
- A. Client with irritable bowel syndrome
- B. Family history of colon polyps
- C. Client with cirrhosis of the liver
- D. History of colon surgery
Correct Answer: B
Rationale: A family history of colon polyps and/or colon cancer is a significant risk factor for developing colon cancer. Individuals with a family history are more likely to develop colon cancer due to genetic predisposition. While other factors like irritable bowel syndrome, cirrhosis of the liver, and history of colon surgery may contribute to an increased risk of colon cancer, having a family history of colon polyps is the highest risk factor. Irritable bowel syndrome does not directly increase the risk of colon cancer. Cirrhosis of the liver is associated with liver cancer rather than colon cancer. A history of colon surgery may reduce the risk of colon cancer in some cases by removing precancerous polyps.
A client complaining of chest pain is prescribed an intravenous infusion of nitroglycerin (Nitro-Bid). After the infusion is initiated, the occurrence of which symptom warrants the nurse discontinuing an intravenous infusion of nitroglycerin?
- A. Frontal headache
- B. Orthostatic hypotension
- C. Decrease in intensity of chest pain
- D. Cool clammy skin
Correct Answer: D
Rationale: The correct answer is 'Cool clammy skin.' This assessment finding indicates decreased cardiac output that could result from excessive vasodilation. Cool clammy skin is a sign of poor perfusion, suggesting that the blood pressure might be dropping too low. Discontinuing the nitroglycerin infusion is crucial to prevent further complications.
Choice A, 'Frontal headache,' is a common side effect of nitroglycerin but not a reason to discontinue the infusion unless severe or persistent. Choice B, 'Orthostatic hypotension,' may occur as a side effect of nitroglycerin but does not necessarily warrant discontinuation unless severe. Choice C, 'Decrease in intensity of chest pain,' is actually an expected therapeutic response to nitroglycerin and indicates improved myocardial perfusion, so it is not a reason to stop the infusion.
Because of the possible nervous system side-effects that occur with isoniazid (Nydrazid) therapy, which supplementary nutritional agent would the nurse teach the client to take as a prophylaxis?
- A. Alpha tocopherol (vitamin E)
- B. Ascorbic acid (vitamin C)
- C. Calcitriol (vitamin D)
- D. Pyridoxine (vitamin B6)
Correct Answer: D
Rationale: Pyridoxine is the correct choice in this scenario because it is used as a prophylaxis to prevent neuritis, a possible nervous system side-effect of isoniazid therapy. Neuritis is a condition that involves inflammation of the nerves and can be a side effect of isoniazid. Pyridoxine, also known as vitamin B6, helps prevent this side effect. Vitamin E (Alpha tocopherol), vitamin C (Ascorbic acid), and vitamin D (Calcitriol) do not specifically address the nervous system side-effects associated with isoniazid therapy, making them incorrect choices.
The client is undergoing progressive ambulation on the third day after a myocardial infarction. Which clinical manifestation would indicate that the client should not be advanced to the next level?
- A. Facial flushing
- B. A complaint of chest heaviness
- C. Heart rate increase of 10 beats/min
- D. Systolic blood pressure increase of 10 mm Hg
Correct Answer: B
Rationale: The correct answer is a complaint of chest heaviness. Onset of chest pain indicates myocardial ischemia, which can be life-threatening. Chest pain in a client post-myocardial infarction should be promptly evaluated, and the activity level should not be advanced. Choices A, C, and D are not the best options because facial flushing, a heart rate increase of 10 beats/min, and a systolic blood pressure increase of 10 mm Hg are not typical indicators of myocardial ischemia or necessarily contraindications for advancing activity levels in this context.
