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?

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.

Correct Answer: D

Rationale: Assessing the dorsalis pedis pulse is crucial after a femoral-popliteal bypass surgery to determine adequate circulation distal to the surgical site. A strong dorsalis pedis pulse indicates sufficient blood flow to the foot, which is essential for monitoring postoperative status. The radial pulse (A) is not the most relevant assessment as it does not provide direct information on circulation in the lower extremities. The femoral pulse (B) may not accurately reflect circulation distal to the surgical site. The apical pulse (C) is used primarily to assess the heartbeat and cardiac function, not circulation in the lower extremities.

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.

Correct Answer: A

Rationale: The correct answer is A: Showing the location of the obstruction and the collateral circulation. An arteriogram is a diagnostic procedure that involves injecting a contrast agent to visualize the blood vessels and identify the location of any obstructions. This helps confirm the diagnosis of occlusive arterial disease by showing where the blockage is located and how collateral circulation is compensating for the reduced blood flow. Choices B, C, and D are incorrect because scanning the extremity, estimating velocity changes with ultrasound, or determining walking distance are not the primary purposes of an arteriogram in diagnosing occlusive arterial disease.

Correct Answer: C

Rationale: The correct answer is C. Moving the legs helps prevent thrombophlebitis and blood clot formation by promoting venous return in clients on bed rest. This prevents stasis and clot formation in the lower extremities. Choices A, B, and D are incorrect because the primary goal of moving the legs is to prevent thrombophlebitis and blood clot formation, rather than preparing for ambulation, promoting elimination, or decreasing pressure ulcer formation. Ambulation preparation involves different exercises, urinary and intestinal elimination are not directly related to leg movements, and pressure ulcer prevention is more related to repositioning and skin care.
