Correct Answer: A

Rationale: The correct answer is A: Administer bronchodilators. During an acute asthma attack, the priority is to open the airways quickly to improve breathing. Bronchodilators work rapidly to dilate the constricted airways, providing immediate relief. Corticosteroids are used for long-term management and take time to be effective. Administering morphine is not recommended as it can depress the respiratory system. Performing an ECG is not necessary in the acute management of an asthma attack.

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: A

Rationale: Correct Answer: A (Iron, folic acid, and B12) Rationale: 1. Iron: Renal failure patients often have anemia due to decreased erythropoietin production. 2. Folic acid and B12: Important for red blood cell production and maturation. 3. Corrects underlying causes of anemia in renal failure patients. Summary: B: Increasing protein doesn't directly address anemia in renal failure. C: Vitamin D and calcium are not primary treatments for anemia in renal failure. D: Calcium and folic acid alone do not address the specific deficiencies seen in renal failure anemia.

Correct Answer: A

Rationale: The correct answer is A because memory loss after a fall can be indicative of a more serious issue like a head injury or neurological problem. A complete mental health examination by the nurse can help assess the extent of memory loss, identify potential causes, and determine appropriate interventions. Referring to a psychometrician (choice B) may not address the immediate health concern. Integrating the mental health examination into history taking and physical examination (choice C) is important but may not be as thorough as a complete mental health examination by a professional. Reassuring the wife that memory loss is normal (choice D) may lead to overlooking a potentially serious health issue.

Correct Answer: D

Rationale: The correct answer is D: Administer corticosteroids. In a client with chest pain and a history of myocardial infarction, the first priority is to address potential inflammation in the myocardium. Corticosteroids help reduce inflammation and stabilize the myocardium, which is crucial in preventing further damage post-myocardial infarction. Administering nitroglycerin (A) is important for vasodilation, but it is typically used after corticosteroids. Morphine (B) and analgesics (C) may provide pain relief but do not address the underlying inflammation. Administering corticosteroids is the most appropriate first step to manage myocardial inflammation and protect the heart tissue.
