Nursing Elites

1. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

2. A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following actions should the nurse take to prevent infection?

• A. Monitor the client's electrolyte levels
• B. Change the TPN tubing every 24 hours
• C. Monitor blood glucose levels every 4 hours
• D. Administer insulin as prescribed

Correct answer: B

Rationale: The correct answer is B. Changing the TPN tubing every 24 hours is crucial in preventing infection by reducing the risk of bacterial contamination. Monitoring electrolyte levels (choice A) is essential but not directly related to preventing TPN-related infections. Monitoring blood glucose levels (choice C) is important for clients receiving TPN, but it is more related to glycemic control than infection prevention. Administering insulin as prescribed (choice D) is necessary for clients with diabetes but is not directly linked to preventing TPN-related infections.

3. A client is constipated and asks the nurse for advice. What should the nurse recommend?

• A. Administer a laxative to relieve discomfort
• B. Increase dietary fiber to promote bowel movements
• C. Advise the client to rest until symptoms resolve
• D. Encourage bed rest to allow bowel function to return

Correct answer: B

Rationale: The correct recommendation for constipation is to increase dietary fiber to promote bowel movements. Dietary fiber helps add bulk to the stool, making it easier to pass and promoting regular bowel movements. Administering a laxative (Choice A) is not the first-line recommendation and should be used cautiously due to potential side effects. Resting until symptoms resolve (Choice C) and encouraging bed rest (Choice D) are not effective interventions for relieving constipation.

4. Which of the following findings should the nurse anticipate in the medical record of a client with a pressure ulcer?

• A. Serum albumin level of 3 g/dL
• B. Braden scale score of 20
• C. Norton scale score of 18
• D. Hemoglobin level of 13 g/dL

Correct answer: A

Rationale: The correct answer is A: Serum albumin level of 3 g/dL. A serum albumin level of 3 g/dL indicates poor nutrition, which is commonly seen in clients with pressure ulcers. Choice B, a Braden scale score of 20, is incorrect because a higher Braden scale score indicates a lower risk of developing pressure ulcers. Choice C, a Norton scale score of 18, is incorrect as it is a tool used to assess the risk of developing pressure ulcers, not a finding in a client with an existing pressure ulcer. Choice D, a hemoglobin level of 13 g/dL, is unrelated to pressure ulcers and does not directly reflect the nutritional status associated with this condition.

5. A client is postoperative following a rhinoplasty, and a nurse is contributing to the plan of care. Which of the following interventions should the nurse recommend?

• A. Administer humidified oxygen
• B. Restrict fluids
• C. Instruct the client to avoid the Valsalva maneuver
• D. Apply heat packs to the nose

Correct answer: C

Rationale: Instructing the client to avoid the Valsalva maneuver is crucial after rhinoplasty to reduce strain and the risk of bleeding. Administering humidified oxygen may not be directly related to postoperative care for rhinoplasty. Restricting fluids is not typically necessary unless specifically indicated by the healthcare provider. Applying heat packs to the nose is contraindicated after rhinoplasty as it can increase the risk of bleeding and should be avoided.
