Three days after admission Ms. CC continued to have frequent stools. Her oral intake of both fluids and solids are poor. Her physician ordered parenteral hyperalimentation. Hyperalimentation solutions are:

Correct Answer: D

Rationale: The correct answer is D: Hyperosmolar solutions used primarily to reverse negative nitrogen balance. Rationale: 1. Hyperalimentation solutions are designed to provide essential nutrients intravenously. 2. Hyperosmolar solutions have a higher osmolarity compared to body fluids, providing concentrated nutrition. 3. Negative nitrogen balance occurs when the body breaks down more protein than it synthesizes, requiring additional protein intake. 4. Hyperosmolar solutions can provide adequate protein and nutrients to reverse negative nitrogen balance. Summary: A: Hypotonic solutions do not increase osmotic pressure, but rather decrease it. B: Hypertonic solutions are not primarily used for hydration in this context. C: Alkalizing solutions are not the primary purpose of hyperalimentation and do not directly address cellular sweating.

Correct Answer: B

Rationale: The correct answer is B: Ambulate with assistance. Ambulating helps prevent further bone loss and strengthens muscles, important for osteoporosis patients. Bedrest can worsen bone density loss. Encouraging fluids and providing a high-protein diet are important for overall health but do not directly address the weakness associated with osteoporosis.

Correct Answer: D

Rationale: The correct answer is D: 2, 4, 5, and 6. 1. Room humidifier (choice 2) helps to keep the air moist, which can ease sinus pressure and discomfort. 2. Hot moist packs (choice 4) can provide relief by reducing congestion and promoting sinus drainage. 3. Percussion and postural drainage (choice 5) can help loosen mucus and improve drainage. 4. Semi-fowler's position (choice 6) can also aid in drainage and reduce sinus pressure. Choices A, B, and C are incorrect because they do not include all the recommended interventions that can help increase comfort in a patient with sinusitis. Each of the incorrect choices is missing at least one crucial recommendation that is beneficial for managing sinusitis symptoms.

Correct Answer: B

Rationale: The correct answer is B because emphysema is characterized by the destruction of the alveoli walls, leading to a loss of elasticity in the lungs. This results in air becoming trapped in the lungs, making it difficult to exhale properly. Explanation for why the other choices are incorrect: A: Inflamed bronchioles causing secretions describe bronchitis, not emphysema. C: Damage to the blood supply isn't a primary feature of emphysema; it's more about lung tissue destruction. D: Large dilated sacs of sputum in the lungs is not an accurate description of emphysema; it's more related to bronchiectasis.

Correct Answer: A

Rationale: The correct answer is A because pursed lip breathing helps to slow down and control the exhalation process, allowing the individual to exhale a smaller volume of air with more force. This helps to prevent air trapping in the lungs, improve oxygen exchange, and reduce shortness of breath. B: Incorrect - Pursed lip breathing does not increase expiration but rather controls it. C: Incorrect - While pursed lip breathing can promote deep breathing and better oxygen exchange, its primary purpose is to regulate exhalation volume. D: Incorrect - Pursed lip breathing does not specifically target the upper thorax but rather facilitates a more efficient breathing pattern by reducing air trapping in the lungs.
