A nurse is caring for a patient who is post-operative following a knee replacement. The nurse should prioritize which of the following interventions?

Correct Answer: A

Rationale: The correct answer is A: Encouraging early ambulation. This is the priority intervention as it helps prevent complications such as blood clots and pneumonia, promotes circulation, and aids in faster recovery. Ambulation also helps maintain joint mobility and muscle strength. Administering pain medications (B) is important but not the priority. Providing wound care (C) and monitoring for infection (D) are important, but ambulation takes precedence in preventing complications.

Correct Answer: D

Rationale: The correct answer is D because all choices (A, B, and C) can increase the risk of STDs. Alcohol use can impair judgment leading to risky sexual behavior. Certain sexual practices (such as unprotected sex or having multiple partners) can directly increase the risk of STD transmission. Oral contraception does not protect against STDs, so individuals relying solely on it may still be at risk. Therefore, all of the above factors can contribute to an increased risk of contracting STDs.

Correct Answer: A

Rationale: The correct answer is A: Chronic kidney disease (CKD). Patients with diabetes and hypertension are at increased risk for developing CKD due to the damaging effects of high blood sugar and elevated blood pressure on the kidneys. The nurse should monitor for signs and symptoms of kidney dysfunction such as proteinuria, elevated creatinine levels, and decreased glomerular filtration rate. B: Chronic pain is not directly related to the patient's history of diabetes and hypertension. While the patient may experience pain as a result of complications from these conditions, it is not the primary complication to monitor for in this case. C: Hypotension, or low blood pressure, is not a common complication associated with diabetes and hypertension. These conditions typically lead to high blood pressure rather than low blood pressure. D: Sepsis is a serious infection that can occur in any patient, but it is not a direct complication specifically related to diabetes and hypertension. Monitoring for sepsis would be important in a broader context but is not

Correct Answer: A

Rationale: Rationale for Correct Answer A: 1. Using the defrost setting on microwave ovens to warm bottles is safe because it ensures even heating without creating hot spots that could burn the baby's mouth. 2. This method helps to preserve the nutrients in the breast milk or formula. 3. It is important to warm the bottle to body temperature to mimic the natural feel of breast milk for the baby's comfort. Summary of Incorrect Choices: B: Feeding the baby partially used bottles after 24 hours can increase the risk of bacterial contamination and foodborne illness. C: Mixing two parts water and one part concentrate for formula concentrate is incorrect as it may dilute the formula, leading to inadequate nutrition for the baby. D: Adding new formula to partially used bottles can alter the balance of nutrients and increase the risk of contamination, affecting the baby's health.

Correct Answer: B

Rationale: The correct answer is B: Administer antibiotics. When caring for a client with severe burns, the first priority is to prevent infection, which can be life-threatening. Administering antibiotics helps reduce the risk of infection. Cleansing and dressing the wounds can come after ensuring infection control. Performing a tracheostomy is not typically the first priority unless there are airway concerns. Administering analgesics is important, but it is not the first priority in this case.

Correct Answer: A

Rationale: The correct answer is A: Administer pain relief. The nurse's first priority is to address pain and ensure the client's comfort and well-being. Pain relief helps reduce distress, improve communication, and prevent complications. Monitoring blood pressure (B) and providing hydration (C) are important but not the immediate priority in severe trauma. Administering a blood transfusion (D) may be necessary but is not the first priority compared to addressing pain and stabilizing the client.

Correct Answer: B

Rationale: The correct answer is B: ondansetron (Zofran). Ondansetron is a selective serotonin receptor antagonist that effectively targets the serotonin receptors in the chemoreceptor trigger zone to relieve nausea and vomiting. It is commonly used in chemotherapy-induced nausea and vomiting. A: Metoclopramide is a dopamine receptor antagonist and primarily used for gastrointestinal motility disorders, not specifically for nausea relief. C: Hydroxyzine is an antihistamine with sedative properties, primarily used for anxiety and itching, not specifically for nausea relief. D: Prochlorperazine is a dopamine receptor antagonist primarily used for treating psychotic disorders, not specifically for nausea relief. In summary, ondansetron is the correct choice as it targets serotonin receptors specifically for relieving nausea and vomiting, whereas the other options focus on different mechanisms of action.

Correct Answer: B

Rationale: The correct answer is B: Provide a source of fast-acting carbohydrate. In hypoglycemia, the priority is to raise blood glucose levels quickly to prevent complications like seizures or loss of consciousness. Fast-acting carbs like juice or glucose tablets are the first-line treatment. Administering insulin (choice A) would lower blood sugar further. Administering an oral hypoglycemic agent (choice C) takes time to work and is not suitable for emergencies. Monitoring blood pressure (choice D) is important but not the priority in this situation.

Correct Answer: A

Rationale: The correct answer is A: Administer epinephrine. This is the first action because epinephrine is the primary treatment for anaphylaxis, a severe allergic reaction that can be life-threatening. It works quickly to reverse the symptoms by constricting blood vessels and opening airways. Administering epinephrine promptly can prevent progression to severe complications such as respiratory distress or cardiovascular collapse. Placing the client in a supine position and administering oxygen (B) may be necessary but should not delay the administration of epinephrine. Administering fluids (C) may help maintain blood pressure but is not the priority in the acute phase of anaphylaxis. Antihistamines (D) are not effective for treating the severe symptoms of anaphylaxis and should not be the first-line treatment.
