Nokea
When assessing an individual with peripheral vascular disease, which clinical manifestation would indicate complete arterial obstruction in the lower left leg?
- A. Aching pain in the left calf.
- B. Burning pain in the left calf.
- C. Numbness and tingling in the left leg.
- D. Coldness of the left foot and ankle.
Correct Answer: D
Rationale: Coldness of the left foot and ankle is the correct clinical manifestation indicating complete arterial obstruction in the lower left leg. Complete arterial obstruction results in reduced blood flow, leading to decreased temperature in the affected area. Aching pain (Choice A) and burning pain (Choice B) are more commonly associated with partial obstructions or ischemia, while numbness and tingling (Choice C) can be indicative of nerve involvement or compromised circulation, but not specifically complete arterial obstruction. The coldness in the foot and ankle is a result of severely reduced blood flow, which impairs the delivery of oxygen and nutrients to the tissues in that area, leading to a lower temperature. This symptom is a critical indicator of a more severe blockage compared to the other options provided.

The client is preparing a morning dose of insulin, which includes 10 units of regular and 22 units of NPH. The nurse is verifying the client's preparation accuracy. What should the syringe read for the correct dose?
- A. 22 units.
- B. 10 units.
- C. 32 units.
- D. 42 units.
Correct Answer: C
Rationale: The correct answer is 32 units. To determine the correct dose, the nurse needs to add the 10 units of regular insulin to the 22 units of NPH, resulting in a total of 32 units. Therefore, the syringe should read 32 units. Choices A, B, and D are incorrect because they do not reflect the accurate total dose required for the morning insulin administration.
A client who had a C-5 spinal cord injury 2 years ago is admitted to the emergency department with the diagnosis of autonomic dysreflexia secondary to a full bladder. Which assessment finding should the nurse expect this client to exhibit?
- A. Complaints of chest pain and shortness of breath
- B. Hypotension and venous pooling in the extremities
- C. Profuse diaphoresis and severe, pounding headache
- D. Pain and burning sensation upon urination and hematuria
Correct Answer: C
Rationale: Autonomic dysreflexia is a life-threatening condition commonly seen in clients with spinal cord injuries above the T6 level. It is characterized by a sudden onset of excessively high blood pressure due to a noxious stimulus below the level of injury, often a distended bladder. The exaggerated sympathetic response leads to vasoconstriction, resulting in symptoms such as profuse diaphoresis (sweating) and a severe, pounding headache. These symptoms are the body's attempt to lower blood pressure. Complaints of chest pain and shortness of breath (Choice A) are not typical findings in autonomic dysreflexia. Hypotension and venous pooling (Choice B) are opposite manifestations of autonomic dysreflexia, which is characterized by hypertension. Pain and burning sensation upon urination and hematuria (Choice D) are indicative of a urinary tract infection and not specific to autonomic dysreflexia.
Which of the following medications is commonly prescribed for hypertension?
- A. Atenolol
- B. Aspirin
- C. Ibuprofen
- D. Metformin
Correct Answer: A
Rationale: The correct answer is Atenolol. Atenolol is a beta-blocker commonly prescribed to manage hypertension due to its ability to reduce the heart rate and lower blood pressure. Options B, C, and D are incorrect because aspirin, ibuprofen, and metformin are not typically used as first-line treatments for hypertension. Aspirin is more commonly used for its antiplatelet effects, ibuprofen is a nonsteroidal anti-inflammatory drug, and metformin is primarily used for managing diabetes.
The client with peripheral artery disease has been prescribed clopidogrel (Plavix). The nurse understands that more teaching is necessary when the client states which of the following?
- A. I should not be surprised if I bruise more easily or if my gums bleed a little when brushing my teeth.
- B. It is important to take this medicine with food to enhance its effectiveness and minimize stomach upset.
- C. I should stop taking Plavix if it makes me feel weak and dizzy.
- D. The doctor prescribed this medicine to make my platelets less likely to stick together and help prevent clots from forming.
Correct Answer: C
Rationale: The correct answer is C. Weakness, dizziness, and headache are common adverse effects of Plavix and should be reported. It is essential to consult a physician before stopping Plavix as it plays a crucial role in preventing platelets from sticking together and forming clots. Choices A, B, and D are incorrect. Choice A is a common side effect of Plavix and does not indicate a need for further teaching. Choice B is incorrect because taking Plavix with or without food can affect its absorption and effectiveness. Choice D correctly explains the purpose of prescribing Plavix to prevent clot formation.
Which of the following is a common complication of hypertension?
- A. Diabetes.
- B. Heart failure.
- C. Kidney failure.
- D. Stroke.
Correct Answer: D
Rationale: The correct answer is D: Stroke. Hypertension can lead to stroke due to the increased pressure on blood vessels in the brain, which can result in reduced blood flow and oxygen to the brain tissue. While choices B (Heart failure) and C (Kidney failure) can be complications of hypertension, they are not as directly associated as stroke. Choice A, Diabetes, is not a direct complication of hypertension but rather a separate condition that can be influenced by various factors. However, stroke is more commonly linked to the increased pressure on blood vessels in the brain in individuals with hypertension.
