Pharmacology and the Nursing Process 9th Edition Test Bank

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.

Correct Answer: D

Rationale: The correct answer is D: Hypovolemia and shock. Rationale: 1. Low blood volume leads to decreased blood pressure and rapid heart rate as compensatory mechanisms. 2. These signs indicate inadequate perfusion due to reduced blood volume. 3. Hypovolemia can progress to shock if not addressed promptly. Summary: A: Compression of blood vessels is not directly related to low blood volume. B: Increasing circulating blood volume would not occur in a client with low blood volume. C: Inadequate renal perfusion is a consequence of hypovolemia, not an implication of decreasing blood pressure and rapid heart rate.

Correct Answer: D

Rationale: The correct answer is D: Whisper voice test. This test is used as an initial screening for hearing loss because it is simple, quick, and easily administered by a nurse. The nurse would whisper words or numbers at a specific distance from the patient to assess their ability to hear and repeat the whispered sounds accurately. This test provides a quick indication of potential hearing impairment. The other choices are incorrect: A: Romberg test assesses balance and not hearing. B: Caloric test evaluates the vestibular system, not hearing. C: Otoscopic examination is used to examine the ear canal and tympanic membrane, not to screen for hearing loss.

Correct Answer: C

Rationale: The correct answer is C because it accurately defines a transient ischemic attack (TIA) as a temporary interruption in blood flow to the brain. This response demonstrates the nurse's knowledge and ability to provide accurate information to the family member. Option A is incorrect because it deflects the question to the doctor without providing any information. Option B is incorrect because it inaccurately states that TIA causes permanent brain damage, which is not true. Option D is also incorrect because it simply restates the abbreviation without providing any explanation of what TIA actually means.

Correct Answer: A

Rationale: The correct answer is A: Use parallel bars or a walker. Before a client with impaired physical mobility gets up, the nurse should provide assistive devices like parallel bars or a walker to ensure safe and supported ambulation. This helps prevent falls and promotes independence. Using incontinence pads (B) is not directly related to mobility. Applying an abdominal binder (C) is not necessary before the client gets up. Using a footboard (D) is more relevant for positioning in bed, not for assisting with ambulation.
