Correct Answer: A

Rationale: Correct answer: A - Hyperkalemia Rationale: 1. In CKD, impaired kidney function leads to decreased potassium excretion, causing hyperkalemia. 2. Hyperkalemia can result in life-threatening cardiac arrhythmias. 3. Monitoring potassium levels is crucial in CKD management. Summary: B: Hypoglycemia - Not typically associated with CKD, more common in diabetes. C: Hyperglycemia - Common in diabetes, but not a typical complication of CKD. D: Hypercalcemia - Uncommon in CKD, more often seen in hyperparathyroidism.

Correct Answer: B

Rationale: The correct answer is B: a set of rules. Novice nurses rely on established guidelines and protocols to make decisions as they lack the experience to rely solely on intuition or journal articles. Rules provide structure and consistency in decision-making, reducing the margin of error. Intuition (choice A) may not be reliable without prior experience. Journal articles (choice C) can be overwhelming and may not directly apply to the specific situation. Advice from supervisors (choice D) can be helpful but may not always be readily available, and it's important for novice nurses to develop their own decision-making skills.

Correct Answer: A

Rationale: The correct answer is A: Administer nitroglycerin. This is the priority intervention because nitroglycerin helps dilate blood vessels, reducing chest pain in clients with heart disease. It improves blood flow to the heart, relieving ischemia. Morphine (B) can mask symptoms and should be used if pain persists after nitroglycerin. Beta blockers (C) are beneficial in chronic management but not for immediate relief. Aspirin (D) helps prevent clot formation but is not the priority in acute chest pain.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. In ARDS, the primary issue is hypoxemia due to impaired gas exchange in the lungs. Administering oxygen helps to increase the oxygen levels in the blood, improving oxygenation to vital organs. Corticosteroids (B) are not indicated as they have not shown consistent benefit in ARDS treatment. Bronchodilators (C) are not effective as ARDS is not primarily a bronchoconstrictive disorder. Applying an ice pack to the chest (D) is not relevant and will not address the underlying hypoxemia. Administering oxygen is the most effective and essential intervention to correct hypoxemia in ARDS.

Correct Answer: A

Rationale: The correct answer is A: Administer glucose. When a client presents with symptoms of hypoglycemia, the nurse should prioritize raising the blood sugar levels immediately to prevent further complications. Administering glucose helps to quickly address the low blood sugar levels and alleviate symptoms. Monitoring blood glucose (B) is important but not the first step in an acute situation. Administering insulin (C) would worsen hypoglycemia. Monitoring for arrhythmias (D) is not the primary concern when dealing with hypoglycemia.
