A nurse is assessing a client following the administration of an initial dose of captopril. Which of the following findings indicates an anaphylactic response?
Laryngeal edema
Fever
Hypertension
Arrhythmia
The Correct Answer is A
Choice A reason: Laryngeal edema is a classic sign of anaphylaxis, a severe and potentially life-threatening allergic reaction. It can lead to difficulty breathing and requires immediate medical attention. Anaphylaxis can occur with any medication, including captopril, especially on initial exposure.
Choice B reason: Fever is not typically a sign of anaphylaxis. While it can be a symptom of various infections or inflammatory processes, it is not indicative of an immediate hypersensitivity reaction.
Choice C reason: Hypertension, or high blood pressure, is not a sign of anaphylaxis. In fact, during an anaphylactic reaction, blood pressure often drops significantly, a condition known as anaphylactic shock.
Choice D reason: Arrhythmia, or an irregular heartbeat, can be associated with various cardiac conditions but is not a specific indicator of anaphylaxis. While severe allergic reactions can affect heart rate, they are more likely to cause hypotension than arrhythmia.

Correct Answer is A
Explanation
Choice A reason: Drawing the regular insulin into the syringe first is correct. When mixing two types of insulin, the clear (regular) insulin should be drawn up before the cloudy (NPH) insulin to prevent contamination.
Choice B reason: Storing prefilled syringes with the needle pointed upward can cause air bubbles to move into the insulin, which can alter the dose when injected. The needle should be pointed downward.
Choice C reason: Shaking the NPH vial vigorously is not recommended as it can create air bubbles and affect the insulin dose. Instead, the vial should be gently rolled between the hands to mix the insulin.
Choice D reason: Inserting the needle at a 15-degree angle is incorrect for subcutaneous injections. A 90-degree angle is typically used unless the patient is very thin, in which case a 45-degree angle may be used.
Correct Answer is A
Explanation
Choice A reason: Checking the pulse distal to the graft is essential to ensure that the graft is patent and that there is adequate blood flow to the distal extremity. A palpable pulse indicates that the graft is functioning properly and not occluded. The absence of a pulse could signify a serious complication, such as thrombosis or stenosis, which requires immediate attention.
Choice B reason: Keeping the left forearm below the level of the heart is not recommended as it can increase venous pressure and swelling, potentially compromising graft function. The extremity should be kept at or above heart level to promote venous return and reduce the risk of edema.
Choice C reason: Collecting blood specimens from the graft is generally avoided to prevent damage to the graft. Blood draws can be performed from other sites to protect the integrity of the graft.
Choice D reason: Splinting the left forearm is not a standard postoperative care measure for an arteriovenous graft. While protecting the graft from injury is important, immobilization with a splint is not necessary and can impede mobility and circulation.
