Sexuality is maintained throughout our lives. Which of the following answers best explains sexuality in an older adult?

Correct Answer: D

Rationale: The correct answer is D because sexuality is a natural and normal aspect of human life, regardless of age or health status. Older adults have the right to express their sexual feelings and desires. This expression can contribute to emotional well-being and quality of life. Choices A and B are incorrect as they suggest a limited view of sexuality in older adults. Choice C is incorrect as it wrongly implies that any expression of sexuality in older adults is a sign of a developmental problem, which is not true. Older adults, like individuals of all ages, have the ability and right to maintain their sexuality.

Correct Answer: A

Rationale: The correct answer is A: Assess the client's level of consciousness. In ARDS, hypoxemia can lead to altered mental status. Assessing the client's level of consciousness is crucial for detecting any neurological changes and ensuring timely intervention. Monitoring urine output (B) is important for assessing renal function but is not a priority in ARDS. Turning the client every two hours (C) is a standard nursing intervention for preventing pressure ulcers but is not directly related to managing ARDS. Maintaining intravenous fluids as ordered (D) is important, but assessing the client's level of consciousness takes precedence in the care of a client with ARDS.

Correct Answer: C

Rationale: The correct answer is C because diffuse bilateral infiltrates or 'white-out' appearance on a chest x-ray are classic findings in Acute Respiratory Distress Syndrome (ARDS) due to widespread alveolar damage and fluid accumulation. This pattern reflects severe impairment of gas exchange. Choice A is incorrect because unilateral infiltrates in the upper lobe are more indicative of conditions like pneumonia or lung cancer. Choice B is incorrect because cardiomegaly with pleural effusion suggests heart failure rather than ARDS. Choice D is incorrect because normal findings despite severe symptoms are not characteristic of ARDS, which presents with significant abnormalities on imaging due to the underlying lung injury.

Correct Answer: B

Rationale: The correct answer is B because a PaO2 of 45 mm Hg indicates hypoxemia, a common feature of acute respiratory failure. In acute respiratory failure, the patient's lungs are unable to provide enough oxygen to meet the body's demands, leading to low oxygen levels in the blood. Shallow breathing (choice A) is a sign of respiratory distress but not specific to acute respiratory failure. A PaCO2 of 34 mm Hg (choice C) is within the normal range and would not indicate acute respiratory failure. A respiratory rate of 32/min (choice D) may indicate respiratory distress but alone is not sufficient to confirm acute respiratory failure.

Correct Answer: D

Rationale: Rationale: Correct Answer (D): PEEP prevents the lung air sacs from collapsing during exhalation. PEEP helps maintain lung recruitment by keeping the air sacs open at the end of expiration, preventing collapse and improving oxygenation. This is crucial in patients with ARDS to prevent atelectrauma and improve gas exchange. Incorrect Choices: A: Incorrect. PEEP does not prevent fibrosis of the lung. Its primary purpose is to maintain lung recruitment. B: Incorrect. PEEP does not push more air into the lungs during inhalation but helps keep the lungs open during exhalation. C: Incorrect. PEEP does not directly control the oxygen percentage delivered by the ventilator; its main role is to maintain lung volume.
