The nurse is observing a client receiving antiplatelet therapy for adverse reactions. Antiplatelet drugs most commonly produce which hypersensitivity reaction?
- A. Difficulty hearing
- B. Confusion
- C. Bronchospasm
- D. Agranulocytosis
Correct Answer: C
Rationale: The correct answer is C: Bronchospasm. Antiplatelet drugs commonly cause hypersensitivity reactions like bronchospasm due to their effects on platelet function. They can trigger an allergic response leading to bronchoconstriction. Difficulty hearing (A) is not a common hypersensitivity reaction to antiplatelet therapy. Confusion (B) is more commonly associated with central nervous system effects rather than hypersensitivity reactions. Agranulocytosis (D) is a severe drop in white blood cells and is not typically a hypersensitivity reaction to antiplatelet drugs.

Which instruction about insulin administration should the nurse give to a client?
- A. “Always follow the same order when drawing the different insulin into the syringe.”
- B. “Shake the vial before withdrawing the insulin.”
- C. “Store unopened vials of insulin in the freezer at temperatures well below freezing.”
- D. “Discard the intermediate-acting insulin if it disappears cloudy.”
Correct Answer: A
Rationale: The correct answer is A because maintaining consistency in the order of drawing different types of insulin into the syringe helps prevent medication errors. When mixing insulins, drawing them in the same sequence ensures the correct dose and prevents contamination.
Explanation:
A: Following the same order ensures accurate dosing and minimizes the risk of mixing up insulins.
B: Shaking the vial can cause air bubbles which can affect the accuracy of the dose.
C: Storing insulin in the freezer can damage the medication and alter its effectiveness.
D: Cloudiness in intermediate-acting insulin is normal and does not indicate it should be discarded.
A client with diabetes mellitus must learn how to self-administer insulin. The physician has prescribed 10 U of U- 100 regular insulin and 35 U of 100-U isophane insulin suspension (NPH) to be taken before breakfast. When teaching the client how to select and rotate insulin injection sites, the nurse should provide which instruction?
- A. “Inject insulin into healthy tissue with large blood vessels and nerves.”
- B. “Rotate injection sites within the same anatomic region, not among different regions.”
- C. “Administer insulin into areas of scar tissue or hypotrophy whenever possible.”
- D. “Administer insulin into sites above muscles that you plan to exercise heavily later that day.”
Correct Answer: B
Rationale: The correct answer is B: “Rotate injection sites within the same anatomic region, not among different regions.” This instruction is important to prevent lipodystrophy and ensure consistent insulin absorption. Rotating sites within the same region helps maintain consistent insulin absorption rates and reduces the risk of developing scar tissue or fatty deposits. Injecting into healthy tissue with large blood vessels and nerves (choice A) can lead to inconsistent absorption. Administering insulin into areas of scar tissue or hypotrophy (choice C) can also disrupt absorption. Injecting into sites above muscles planned for exercise (choice D) can lead to unpredictable insulin absorption. Rotation within the same region optimizes insulin delivery and prevents complications.
A 36-year-old man is scheduled for a unilateral orchiectomy for treatment of testicular cancer. He is withdrawn and does not interact with the nurse. Which action is most appropriate?
- A. Identify the problem with a nursing diagnosis of impaired communication related to the diagnosis of cancer
- B. Set a patient outcome that the patient will verbalize his concerns about his diagnosis
- C. Ask the patient whether he is worried about future sexual functioning
- D. Say, “You seem quiet. Are you feeling concerned about your diagnosis or treatment?”
Correct Answer: D
Rationale: Step-by-step rationale for choosing answer D as correct:
1. Acknowledges patient's withdrawn behavior
2. Demonstrates empathy and concern
3. Open-ended question allows patient to express feelings
4. Encourages patient to communicate concerns
Summary:
- Option A assumes a specific problem without patient input
- Option B focuses on verbalization, not necessarily addressing underlying concerns
- Option C makes assumptions about patient's worries without allowing him to express himself
A pregnant client with hypertension and cardiac dysrhythmias is admitted to the hospital. Which of the following imbalances should the nurse check for?
- A. Metabolic acidosis
- B. Hypernatremia
- C. Hypomagnesemia
- D. Hypercalcemia
Correct Answer: C
Rationale: The correct answer is C: Hypomagnesemia.
1. Hypertension and cardiac dysrhythmias can be exacerbated by low magnesium levels.
2. Magnesium plays a crucial role in maintaining normal heart rhythm and blood pressure.
3. Hypomagnesemia can lead to cardiac arrhythmias and worsen hypertension.
4. Metabolic acidosis (A) is not directly related to hypertension and dysrhythmias.
5. Hypernatremia (B) and hypercalcemia (D) are less likely to be associated with cardiac issues in this context.
In summary, checking for hypomagnesemia is essential due to its direct impact on the client's hypertension and cardiac dysrhythmias.
Minda, a 65-year old female has been admitted with a left hemisphere stroke. Which behavioral change would the nurse expect to find upon assessment?
- A. impulsive, unsafe activity
- B. motor deficits on the right eye
- C. motor deficits on the left side of the body
- D. error in word choices
Correct Answer: D
Rationale: The correct answer is D: error in word choices. In left hemisphere stroke, language and speech centers are usually affected, leading to aphasia. This results in errors in word choices, difficulty expressing thoughts, and understanding language. Impulsivity and unsafe activities (choice A) are more commonly associated with frontal lobe damage. Motor deficits on the right eye (choice B) and left side of the body (choice C) are typical in strokes affecting the motor cortex, which is located in the contralateral hemisphere.
