Which of the following is a complication of compartment syndrome?
- A. Hemorrhage
- B. Pain and tissue damage
- C. Increased limb function
- D. Chronic kidney disease
Correct Answer: B
Rationale: The correct answer is B: Pain and tissue damage. Compartment syndrome occurs due to increased pressure within the muscle compartments, leading to pain and tissue damage. Hemorrhage (choice A) is not a typical complication of compartment syndrome. Increased limb function (choice C) is not a complication but rather a potential improvement if the condition is managed appropriately. Chronic kidney disease (choice D) is unrelated to compartment syndrome.

A patient with a history of venous thromboembolism is prescribed hormone replacement therapy (HRT). What should the nurse discuss with the patient regarding the risks of HRT?
- A. HRT is associated with an increased risk of venous thromboembolism, so the patient should be aware of the signs and symptoms of blood clots.
- B. HRT can decrease the risk of osteoporosis, but the patient should also be aware of the increased risk of venous thromboembolism.
- C. HRT may increase the risk of breast cancer, so the patient should undergo regular breast exams.
- D. HRT can improve mood and energy levels, but it also carries a risk of cardiovascular events.
Correct Answer: A
Rationale: The correct answer is A. Hormone replacement therapy (HRT) is indeed associated with an increased risk of venous thromboembolism. Therefore, patients should be educated about the signs and symptoms of blood clots and advised to seek immediate medical attention if they occur. Choice B is incorrect because although HRT may decrease the risk of osteoporosis, the focus of concern in this case is the increased risk of venous thromboembolism. Choice C is incorrect as it mentions the risk of breast cancer, which is not the primary concern when discussing HRT with a patient with a history of venous thromboembolism. Choice D is also incorrect as it mentions cardiovascular events, which are not the main focus of risk associated with HRT in this scenario.
What is a characteristic of coronary artery disease (CAD)?
- A. The build-up of infectious by-products in the lymph nodes
- B. Insufficient delivery of oxygenated blood to the myocardium
- C. Insufficient delivery of carbon dioxide to the lungs
- D. The build-up of bile in the stomach and gallbladder
Correct Answer: B
Rationale: The correct characteristic of coronary artery disease (CAD) is the insufficient delivery of oxygenated blood to the myocardium. CAD is a condition where the coronary arteries become narrowed or blocked, leading to reduced blood flow to the heart muscle. This lack of oxygenated blood can result in chest pain, known as angina, and if a coronary artery becomes completely blocked, it can cause a heart attack. Choices A, C, and D are incorrect. Choice A refers to an issue related to the lymphatic system, choice C is about gas exchange in the lungs, and choice D describes a problem with bile accumulation in the digestive system, none of which are characteristics of CAD.
Which of the following describes inflammation of the bladder lining?
- A. Incontinence
- B. Pyelonephritis
- C. Urinary calculi
- D. Cystitis
Correct Answer: D
Rationale: The correct answer is D, Cystitis. Cystitis specifically refers to the inflammation of the bladder lining. Choice A, Incontinence, refers to the loss of bladder control and is not related to inflammation. Choice B, Pyelonephritis, is the inflammation of the kidney and renal pelvis, not the bladder lining. Choice C, Urinary calculi, refers to the formation of stones in the urinary tract and is not related to bladder inflammation.
A male patient is being treated with sildenafil (Viagra) for erectile dysfunction. What condition would contraindicate the use of this medication?
- A. Peptic ulcer disease
- B. History of myocardial infarction
- C. Recent use of antihypertensive medications
- D. Use of nitrates
Correct Answer: D
Rationale: The correct answer is D: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, and the combination can lead to a dangerous drop in blood pressure. Choice A, peptic ulcer disease, is not a contraindication for sildenafil use. Choice B, a history of myocardial infarction, is not a contraindication unless the patient is also taking nitrates. Choice C, recent use of antihypertensive medications, is not a contraindication but requires caution as the combination can lead to additive effects lowering blood pressure.
Which of the following organs are primarily affected by poorly managed hypertension?
- A. The bladder and urethra
- B. The brain and skin
- C. The heart and kidneys
- D. The stomach and intestines
Correct Answer: C
Rationale: Poorly managed hypertension primarily affects the heart and kidneys. The heart is at risk of conditions like heart failure due to the increased workload from elevated blood pressure. The kidneys can suffer damage from longstanding hypertension, leading to kidney disease. Choices A, B, and D are incorrect because the bladder, urethra, brain, skin, stomach, and intestines are not the primary organs affected by poorly managed hypertension.
