Correct Answer: A

Rationale: Nausea is a common symptom of intolerance to enteral feedings. When a client experiences nausea during enteral feeding, it can indicate issues such as feeding tube placement problems, formula intolerance, or gastroparesis. Nausea can lead to vomiting and further complications if not addressed promptly. Decreased heart rate, weight gain, and fever are not typically associated with intolerance to enteral feedings and would not be the primary indicators for this situation.

Correct Answer: B

Rationale: A heart rate of 120 beats per minute indicates tachycardia, which can be a sign of dehydration and requires intervention. A heart rate of 80 beats per minute is within the normal range and does not indicate dehydration. A blood pressure of 110/70 mmHg is considered normal. A respiratory rate of 16 breaths per minute is also within the normal range and does not point towards dehydration.

Correct Answer: B

Rationale: Edema at the IV site is a common sign of infiltration, where fluid leaks into the surrounding tissue. Bruising at the IV site (Choice A) is more indicative of hematoma formation, warmth along the IV site (Choice C) may suggest infection, and pallor at the IV site (Choice D) is not a typical sign of infiltration.

Correct Answer: B

Rationale: The correct answer is B: 'Use pursed-lip breathing during activities.' Pursed-lip breathing improves oxygenation by keeping airways open longer, facilitating better exhalation of carbon dioxide. Choice A is incorrect because avoiding physical activity can lead to deconditioning and worsen oxygenation. Choice C is irrelevant to improving oxygenation in COPD. Choice D is not directly related to improving oxygenation in COPD; weight-bearing exercises are important for bone health but not for oxygenation.

Correct Answer: B

Rationale: Urinary incontinence is a risk factor for developing pressure injuries as it can lead to skin breakdown due to constant exposure to moisture and irritation. Increased fluid intake is important for hydration and overall health but is not directly linked to pressure injuries. Poor nutrition can impair wound healing but is not a direct risk factor for pressure injuries. Immobility can contribute to the development of pressure injuries but is not as directly related as urinary incontinence.
