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, anaphylactic shock and angioedema, as it is the most severe complication of allergies and can be life-threatening. Anaphylactic shock can lead to airway constriction, severe drop in blood pressure, and organ failure. Angioedema can cause swelling of the face, lips, and throat, leading to difficulty breathing. Bronchitis (A) is a respiratory condition that can occur due to allergies but is not typically life-threatening. Cardiac arrest (C) is a serious complication but not directly related to allergies. Asthma and nasal polyps (D) are common allergic conditions but are not as immediately life-threatening as anaphylactic shock.

Correct Answer: C

Rationale: The correct answer is C because TPN (Total Parenteral Nutrition) is indeed given to patients with fluid restrictions, as it provides complete nutrition including fluids, electrolytes, and nutrients. On the other hand, PPN (Peripheral Parenteral Nutrition) is used for patients without fluid restrictions as it provides partial nutrition. A is incorrect because TPN is typically for long-term use and PPN for short-term use. B is incorrect as the caloric requirement does not determine the type of parenteral nutrition. D is incorrect because both TPN and PPN can be used for patients who are unable to eat orally.

Correct Answer: D

Rationale: The correct answer is D because using two pillows to raise the head can increase the risk of venous stasis and thrombosis in a client with polycythemia vera. This condition involves an increased production of red blood cells, leading to thicker blood and potential clot formation. Elevating the head too much can impede blood flow, exacerbating the risk of clotting. Choices A, B, and C are all appropriate statements indicating good self-care practices and physical activity, which are beneficial for clients with polycythemia vera to improve circulation and overall health.

Correct Answer: A

Rationale: The correct answer is A because a normal respiratory rate for an adult is typically between 12-20 breaths per minute. A respiratory rate of 18 falls within this range, indicating adequate respiratory function. Choice B is incorrect because an oxygen saturation of 91% is below the normal range of 95-100%, suggesting potential respiratory insufficiency. Choice C is incorrect as frank blood suction from the tube indicates a serious issue such as bleeding, not adequate respiratory condition. Choice D is also incorrect as the presence of a moderate amount of tracheobronchial secretions may indicate a respiratory infection or other respiratory issue, not necessarily adequate respiratory condition.

Correct Answer: D

Rationale: The correct answer is D: Subclavian veins. Lymph returns to the blood through the subclavian veins because they receive lymphatic drainage from the thoracic duct and right lymphatic duct. Lymphatic vessels merge into lymphatic ducts, which empty into the subclavian veins, allowing lymph to re-enter the bloodstream. The carotid arteries (A) carry oxygen-rich blood to the brain, the aorta (C) is the main artery of the body carrying oxygenated blood from the heart, and the inferior vena cava (B) returns deoxygenated blood from the lower body to the heart. Therefore, choices A, B, and C are incorrect as they are not involved in the return of lymph to the blood.

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:

Rationale: Correct Answer: B: Ask about the chief concerns or problems. Rationale: After setting the agenda, the nurse should proceed by asking about the patient's chief concerns or problems to focus the interview on the patient's needs. This step helps in gathering important information and establishing rapport. Introductions are usually done at the beginning of the interview, so it is not the next step. Explaining that the interview will be over in a few minutes can create anxiety and hinder open communication. Telling the patient about administering medications in 1 hour is not relevant at this point in the interview.

Correct Answer: B

Rationale: The correct answer is B: Apply insect repellent to clothing and exposed skin. This advice helps prevent insect bites, reducing the risk of recurrence. Insect repellent creates a barrier against insects, hence minimizing the chances of getting bitten. Other choices are incorrect as they do not directly address the prevention of insect bites. Choice A is vague and does not provide a specific preventive measure. Choice C is incorrect as thick woollen clothing may not necessarily prevent insect bites. Choice D, sunscreen lotion, protects against UV rays, not insect bites.
