Pharmacology and the Nursing Process 9th Edition Test Bank

Correct Answer: D

Rationale: The correct answer is D: Preventing bone injury. In multiple myeloma, abnormal plasma cells can weaken bones, leading to fractures. Preventing bone injury involves educating the client on fall prevention, avoiding heavy lifting, and ensuring a safe environment. Monitoring respiratory status (A) is not the priority in multiple myeloma. Restricting fluid intake (B) is not directly related to managing multiple myeloma. Balancing rest and activity (C) is important for overall well-being but does not directly address the specific needs of a client with multiple myeloma.

Correct Answer: D

Rationale: The correct answer is D, the bicarbonate-carbonic system. This buffer system is crucial in maintaining the body's pH balance. When CO2 combines with water in the blood, it forms carbonic acid, which dissociates into bicarbonate ions and hydrogen ions. Bicarbonate acts as a base, accepting excess hydrogen ions to prevent a decrease in pH. Hemoglobin and plasma proteins primarily function as transport molecules, not as buffer systems. Phosphate buffer system is present in intracellular fluids, not as commonly in the body. The bicarbonate-carbonic system is the most prevalent buffer system in the blood and plays a vital role in regulating blood pH.

Correct Answer: A

Rationale: The correct answer is A: Inform the physician immediately. This is important because finding a lump in the breast could be a sign of breast cancer, so prompt medical evaluation is crucial. Checking after the next menstrual cycle (B) may delay diagnosis and treatment. Squeezing the nipple (C) can cause harm and is not a reliable method for assessing a lump. Using a heating pad (D) is not recommended as it may mask symptoms and delay proper evaluation. Early detection and intervention are key in improving outcomes for breast cancer.

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: B

Rationale: The correct answer is B because it provides a specific action (offering water) at regular intervals (every 2 hours) to promote hydration, which is a clear and measurable nursing intervention. Choice A is too prescriptive and lacks flexibility. Choice C is reactive and not proactive. Choice D is vague and lacks specific guidance on how to achieve the desired outcome. By offering water consistently, the nurse ensures proactive care and helps meet the client's hydration needs effectively.
