Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?
- A. skin
- B. adipose tissue
- C. skeletal muscle
- D. myocardium
Correct Answer: D
Rationale: The correct answer is 'myocardium.' Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being heart muscle, receives the highest amount of cardiac output and thus the highest amount of a drug. Choices A, B, and C are incorrect because the skin and adipose tissue are poorly perfused, while skeletal muscle is less perfused compared to vital organs like the myocardium.

A 10-year-old boy has been diagnosed with a congenital heart defect. Which of the following clinical signs does not indicate CHF?
- A. Increased body weight
- B. Elevated heart rate
- C. Lower extremity edema
- D. Compulsive behavior
Correct Answer: D
Rationale: Compulsive behavior is not a clinical sign typically associated with congestive heart failure (CHF). CHF commonly presents with symptoms such as increased body weight due to fluid retention, elevated heart rate as the heart works harder to pump blood effectively, and lower extremity edema caused by fluid buildup. While behavioral changes can occur in response to illness, compulsive behavior is not a typical indicator of CHF. Choices A, B, and C are more commonly linked to CHF and should be monitored in patients with this condition.
Following a classic cholecystectomy resection for multiple stones, the PACU nurse observes serosanguinous drainage on the dressing. The most appropriate intervention is to:
- A. notify the physician of the drainage.
- B. change the dressing.
- C. reinforce the dressing.
- D. apply an abdominal binder
Correct Answer: C
Rationale: Serosanguinous drainage is expected after a classic cholecystectomy resection. The appropriate intervention is to reinforce the dressing to maintain pressure and promote clot formation. Changing the dressing prematurely increases the risk of infection as it disturbs the wound. Applying an abdominal binder is not indicated as it can interfere with visualizing the dressing and assessing for any signs of bleeding or infection. Notifying the physician is not necessary at this point unless there are signs of excessive bleeding or other concerning symptoms.
How does cancer affect pain tolerance in elderly clients?
- A. Remain constant.
- B. Decrease.
- C. Increase.
- D. Cancer has no impact on pain tolerance in elderly clients.
Correct Answer: B
Rationale: Pain tolerance in elderly clients with cancer is likely to decrease due to factors such as diminished adaptative capacity, increased physical discomfort, and the psychological impact of the disease. Cancer is known to cause various physical and emotional stressors that can lower the pain threshold, leading to a decrease in pain tolerance. Choices A, C, and D are incorrect because cancer and its associated effects typically result in a decrease in pain tolerance rather than remaining constant, increasing, or having no impact.
Which of the following nursing diagnoses is most appropriate for a client with a new colostomy?
- A. Excess Fluid Volume
- B. Risk for Aspiration
- C. Disturbed Body Image
- D. Urinary Retention
Correct Answer: C
Rationale: Disturbed Body Image is the most appropriate nursing diagnosis for a client with a new colostomy. A new colostomy can significantly impact a person's body image and self-esteem due to the physical changes it brings. This can lead to emotional distress, adjustment issues, and concerns about body image. Excess Fluid Volume, Risk for Aspiration, and Urinary Retention are not directly related to the psychosocial impact of a new colostomy and are therefore not as relevant in this context. While Excess Fluid Volume, Risk for Aspiration, and Urinary Retention are important nursing diagnoses, they are not the priority when considering the psychological and emotional effects of a new colostomy.
Which of the following statements describes the purpose of client restraint?
- A. Restraints are a nursing measure used to maintain client control.
- B. Restraints are an emergency intervention taken as a last resort to protect a client from imminent danger.
- C. Restraints are a therapeutic measure designed to positively reinforce client behavior.
- D. Restraints are an emergency measure that can only be taken by a nurse under the direct supervision of a physician.
Correct Answer: B
Rationale: The correct answer is B. Restraints are used as an emergency intervention when all other options to protect a client from imminent danger have been exhausted. Restraints should only be used as a last resort to ensure the safety of the client and others. Choices A, C, and D are incorrect because restraints are not used to maintain control, reinforce behavior, or are exclusively taken under direct physician supervision. It is crucial to remember that restraint use should always be based on careful assessment, documentation, and adherence to legal and ethical guidelines.
