A client with chronic heart failure is experiencing dyspnea and has an oxygen saturation of 88%. Which position is most appropriate to improve oxygenation?
- A. Supine with legs elevated
- B. High Fowler's position
- C. Prone with pillows under the chest
- D. Side-lying with head flat
Correct Answer: B
Rationale: The correct answer is B: High Fowler's position. High Fowler's position is the most appropriate for a client with chronic heart failure experiencing dyspnea and low oxygen saturation. This position helps improve lung expansion and oxygenation by maximizing chest expansion and allowing better ventilation. Choice A, supine with legs elevated, may worsen dyspnea by reducing lung expansion. Choice C, prone with pillows under the chest, is not suitable for a client experiencing dyspnea as it may further compromise breathing. Choice D, side-lying with head flat, does not facilitate optimal lung expansion and is not the best choice for improving oxygenation in this scenario.

Which of the following is a priority assessment for a client receiving intravenous vancomycin?
- A. Respiratory rate
- B. Blood pressure
- C. Urine output
- D. Hearing acuity
Correct Answer: D
Rationale: The correct answer is D, Hearing acuity. Vancomycin is known to cause ototoxicity, which can result in hearing loss. Monitoring the client's hearing acuity is crucial to detect any early signs of ototoxicity. Assessing respiratory rate, blood pressure, and urine output are important assessments in general patient care but are not the priority when specifically monitoring for vancomycin-induced ototoxicity.
A male client with acquired immune deficiency syndrome (AIDS) and Pneumocystis carinii pneumonia has a CD4+ T cell count of 200 cells/microliter. The client asks the nurse why he keeps getting these massive infections. Which pathophysiologic mechanism should the nurse describe in response to the client's question?
- A. Bone marrow suppression of white blood cells causes insufficient cells to phagocytize organisms.
- B. Exposure to multiple environmental infectious agents overburdens the immune system until it fails.
- C. The humoral immune response lacks B cells that form antibodies and opportunistic infections result.
- D. Inadequate numbers of T lymphocytes are available to initiate cellular immunity and macrophages.

A client with Parkinson's disease is experiencing difficulty swallowing. Which intervention should the nurse implement to prevent aspiration?
- A. Encourage the client to eat quickly.
- B. Provide a straw for liquids.
- C. Place the client in an upright position during meals.
- D. Offer thin liquids.
Correct Answer: C
Rationale: Placing the client in an upright position during meals is the correct intervention to prevent aspiration in a client with Parkinson's disease. This position helps facilitate swallowing and reduces the risk of aspiration. Choice A is incorrect because encouraging the client to eat quickly can increase the risk of choking and aspiration. Choice B is not the best option as straws may not prevent aspiration effectively. Choice D is incorrect as thin liquids can actually increase the risk of aspiration in individuals with swallowing difficulties.
A woman with chronic osteoarthritis is complaining of knee pain. Which pathophysiological process is contributing to her pain?
- A. Inflammation of the synovial membrane.
- B. Degeneration of the cartilage in the joint.
- C. Joint inflammation occurs when chondrocyte injury destroys joint cartilage, producing osteophytes.
- D. Formation of uric acid crystals in the joint space.
Correct Answer: C
Rationale: The correct answer is C. In osteoarthritis, the breakdown of cartilage in the joints leads to chondrocyte injury, which results in the destruction of joint cartilage and the production of osteophytes. This process causes joint inflammation and pain. Choice A is incorrect because osteoarthritis primarily involves the articular cartilage rather than the synovial membrane. Choice B is incorrect as it describes the degeneration of cartilage but does not explain the specific pathophysiological process contributing to pain in osteoarthritis. Choice D is incorrect as the formation of uric acid crystals is characteristic of gout, not osteoarthritis.
Based on this strip, what is the interpretation of this rhythm?
- A. Atrial fibrillation.
- B. Ventricular tachycardia.
- C. Normal sinus rhythm.
- D. Second-degree heart block.
Correct Answer: C
Rationale: The correct answer is C, Normal sinus rhythm. Normal sinus rhythm is characterized by a regular rhythm, normal P waves, and a consistent PR interval. In this context, the strip likely shows a normal ECG pattern with these characteristics, indicating a healthy heart rhythm. Choices A, B, and D are incorrect. Atrial fibrillation would show an irregularly irregular rhythm with no discernible P waves. Ventricular tachycardia would display wide QRS complexes and a fast heart rate. Second-degree heart block would exhibit intermittent dropped QRS complexes.
