A nurse is teaching a client about using a continuous positive airway pressure (CPAP) device to treat obstructive sleep apnea. Which of the following information should the nurse include in the teaching?
- A. It delivers a preset amount of inspiratory pressure throughout the breathing cycle
- B. It has a continuous adjustment feature that changes the airway pressure throughout the cycle
- C. It delivers a preset amount of airway pressure throughout the breathing cycle
- D. It delivers positive pressure at the end of each breath
Correct Answer: C
Rationale: The correct answer is C because a CPAP device delivers a preset amount of positive airway pressure continuously throughout all inspiration and expiration cycles. Choice A is incorrect because CPAP does not deliver inspiratory pressure at the beginning of each breath; it provides continuous positive pressure. Choice B is incorrect because CPAP typically delivers a constant pressure rather than having a feature that changes pressure throughout the cycle. Choice D is incorrect as CPAP does not deliver positive pressure specifically at the end of each breath; it maintains a consistent pressure throughout the breathing cycle.

A nurse is providing teaching to a client who was newly diagnosed with nephrotic syndrome. Which of the following statements should indicate to the nurse that the client understands the teaching?
- A. I can expect swelling in my hands and on my face.
- B. The amount of protein in my blood is high.
- C. I might have some pain and gas in my stomach from this condition.
- D. I will use a soft bristle toothbrush to prevent bleeding gums.
Correct Answer: A
Rationale: The correct answer is A. Nephrotic syndrome leads to edema, especially of the face and dependent areas, due to the loss of protein in the urine. Choice B is incorrect because nephrotic syndrome leads to protein loss in the urine, not an increase in blood protein levels. Choice C is incorrect as stomach pain and gas are not typical symptoms of nephrotic syndrome. Choice D is incorrect as using a soft bristle toothbrush is not directly related to the manifestations of nephrotic syndrome.
A nurse is developing a plan of care for a client who will be placed in halo traction following surgical repair of the cervical spine. Which of the following interventions should the nurse include in the plan?
- A. Inspect the pin site every 4 hours
- B. Monitor the client's skin under the halo vest
- C. Ensure two personnel hold the halo device when repositioning the client
- D. Apply powder to the client's skin under the vest to decrease itching
Correct Answer: B
Rationale: The correct answer is to monitor the client's skin under the halo vest. This is important to assess for signs of skin issues such as excessive sweating, redness, or blistering, which can lead to skin breakdown and infection. Choice A is incorrect because while inspecting the pin site is important, it should be done more frequently than every 4 hours. Choice C is incorrect as the halo device should be supported by the client's body weight, not personnel, when repositioning. Choice D is incorrect because applying powder frequently can increase the risk of skin irritation and infection.
A nurse is teaching a client who has hypertension about dietary modifications to help control blood pressure. Which of the following food choices should the nurse recommend as the best choice for the client to include in their diet?
- A. 1 packet of reconstituted dry onion soup
- B. 3 oz of lean cured ham
- C. 3 oz of chicken breast
- D. ½ cup of canned baked beans
Correct Answer: C
Rationale: For a client with hypertension, a low sodium diet is recommended to help control blood pressure. Among the food choices provided, the best option is 3 oz of chicken breast. Chicken breast is lean protein with lower sodium content compared to other choices. It is a healthier option for managing hypertension. Reconstituted dry onion soup (Choice A) and canned baked beans (Choice D) typically contain higher amounts of sodium, which can be detrimental for blood pressure management. Lean cured ham (Choice B) also tends to have a higher sodium content, making it less suitable for a client with hypertension.
A nurse in an emergency department is caring for a client who has sustained multiple injuries. The nurse observes the client's thorax moving inward during inspiration and outward during expiration. The nurse should suspect which of the following injuries?
- A. Flail chest
- B. Hemothorax
- C. Pulmonary contusion
- D. Pneumothorax
Correct Answer: A
Rationale: The correct answer is A: Flail chest. Flail chest results from multiple rib fractures, causing paradoxical chest movement where the injured part moves inward during inspiration and outward during expiration, interfering with ventilation. Choice B, Hemothorax, involves blood in the pleural cavity and does not typically cause paradoxical chest movement. Choice C, Pulmonary contusion, is a bruise to the lung tissue and does not present with paradoxical chest movement. Choice D, Pneumothorax, is the presence of air in the pleural space, leading to lung collapse, but it does not demonstrate paradoxical chest movement like in flail chest.
A nurse is caring for a client who has syndrome of inappropriate antidiuretic hormone (SIADH) and is receiving 3% sodium chloride via continuous IV. Which of the following laboratory findings should the nurse identify as an indication that the SIADH is resolving?
- A. Urine specific gravity 1.020
- B. Sodium 119 mEq/L
- C. BUN 8 mg/dL
- D. Calcium 8.7 mg/dL
Correct Answer: A
Rationale: A urine specific gravity of 1.020 is within the expected reference range and indicates that the kidneys are appropriately concentrating urine, which is a sign that the syndrome of inappropriate antidiuretic hormone (SIADH) is resolving. A low sodium level (choice B) is associated with SIADH, so a sodium level of 119 mEq/L is not indicative of resolution. BUN (choice C) and calcium levels (choice D) are typically not directly related to SIADH resolution.
