1. A client has a long history of hypertension. Which category of medication would the nurse expect to be ordered to avoid chronic kidney disease (CKD)?

Correct answer: D

Rationale: The correct answer is D, Angiotensin-converting enzyme (ACE) inhibitor. ACE inhibitors inhibit the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. By blocking this conversion, ACE inhibitors promote vasodilation and improve perfusion to the kidneys. Additionally, ACE inhibitors block the breakdown of bradykinin and prostaglandin, further contributing to vasodilation. They also lead to increased renin and decreased aldosterone levels. These effects help in reducing blood pressure and protecting the kidneys in clients with hypertension. Antibiotics are used to fight infections, histamine blockers reduce inflammation, and bronchodilators widen the bronchi, none of which address the underlying processes involved in slowing the progression of chronic kidney disease (CKD) in hypertensive clients.

2. What most likely led to the 67-year-old woman who lives alone tripping on a rug in her home and fracturing her hip?

Correct answer: C

Rationale: The correct answer is C. Osteoporosis, caused by hormonal changes in later life, is the most likely predisposing factor for the fracture in the proximal end of her femur. Osteoporosis leads to reduced bone density, making bones more fragile and susceptible to fractures, especially in the elderly. Choices A, B, and D are less likely to directly lead to a hip fracture in this scenario. Failing eyesight (choice A) could contribute to the fall but is not the main predisposing factor for the fracture. Renal osteodystrophy (choice B) and cardiovascular changes (choice D) are less commonly associated with hip fractures compared to osteoporosis in elderly women.

3. The client admitted with peripheral vascular disease (PVD) asks the nurse why her legs hurt when she walks. The nurse bases a response on the knowledge that the main characteristic of PVD is:

Correct answer: A

Rationale: The correct answer is A: 'Decreased blood flow.' In peripheral vascular disease (PVD), there is a narrowing or blockage of blood vessels, leading to reduced blood flow to the extremities. This decreased blood flow results in inadequate oxygen supply to the muscles, causing pain, especially during physical activity when oxygen demand increases. Choice B, 'Increased blood flow,' is incorrect because PVD is characterized by impaired blood circulation rather than increased flow. Choice C, 'Slow blood flow,' is not precise as PVD involves a more significant reduction in blood flow. Choice D, 'Thrombus formation,' is related to the formation of blood clots within vessels, which can be a complication of PVD but is not its main characteristic.

4. The nurse is providing teaching to a patient who will begin taking a cephalosporin to treat an infection. Which statement by the patient indicates a need for further teaching?

Correct answer: A

Rationale: Patients should take all of an antibiotic regimen even after symptoms clear to ensure complete treatment of the infection.

5. The healthcare provider is assessing an older Caucasian male who has a history of peripheral vascular disease. The healthcare provider observes that the man's left great toe is black. The discoloration is probably a result of:

Correct answer: C

Rationale: Gangrene refers to dead, blackened tissue, often a result of chronic ischemia in clients with peripheral vascular disease. Atrophy (Choice A) is the wasting away or decrease in size of tissue or organ. Contraction (Choice B) refers to the shortening or tightening of a muscle or other body part. Rubor (Choice D) is a red discoloration of the skin, often associated with inflammation or poor circulation, but not typically presenting as blackening like gangrene.
