Correct Answer: C

Rationale: The correct answer is C because monitoring vital signs and fluid status is crucial in managing chronic heart failure. This intervention helps in assessing the patient's condition, detecting any signs of deterioration, and ensuring appropriate fluid balance. Administering diuretics (A) may be necessary but should be based on the patient's fluid status. Encouraging rest (B) is important, but monitoring vital signs takes precedence. Teaching about dietary changes (D) is essential, but ensuring the patient's immediate stability through monitoring is the priority.

Correct Answer: A

Rationale: The correct answer is A: Secure the airway. This is the highest priority for a nurse treating a client with a stab wound to the chest because airway management is crucial for ensuring the client can breathe effectively. If the airway is compromised, the client may not be able to oxygenate properly, leading to serious complications or even death. Administering oxygen (choice B) can help with oxygenation but is not as critical as ensuring the airway is clear. Turning the client (choice C) or applying an abdominal binder (choice D) are not appropriate actions for a stab wound to the chest and would not address the immediate life-threatening issue of airway compromise.

Correct Answer: B

Rationale: The correct answer is B: hamburgers. Clients with hypercholesterolemia should decrease their intake of foods high in saturated fats, like hamburgers. Saturated fats can raise LDL cholesterol levels. Broiled catfish (A) is a lean protein option, wheat bread (C) is a good source of fiber, and fresh apples (D) are a healthy fruit choice. Hamburgers (B) typically contain high levels of saturated fats from red meat and processed ingredients, making them a less ideal choice for individuals with high cholesterol.

Correct Answer: B

Rationale: The correct answer is B: Asthma. Wheezing is a high-pitched whistling sound heard during expiration caused by narrowed airways in conditions like asthma. Pneumonia (A) typically presents with crackles, not wheezes. Pulmonary embolism (C) may cause sudden chest pain and shortness of breath but not wheezing. Pleural effusion (D) results in decreased breath sounds, not wheezes.

Correct Answer: D

Rationale: The correct answer is D: unexplained vaginal bleeding. This is a contraindication for hormone replacement therapy as it may indicate underlying conditions that need to be addressed before starting hormone therapy to avoid potential risks. Vaginal bleeding could be a sign of endometrial hyperplasia or cancer, which can be exacerbated by hormone therapy. Choices A, B, and C are not contraindications for hormone replacement therapy. Family history of stroke may influence the choice of therapy but not necessarily contraindicate it. Ovaries removed before age 45 and frequent hot flashes/night sweats are common indications for hormone replacement therapy to alleviate symptoms of menopause.
