Correct Answer: C

Rationale: The correct answer is C: Gastric ulcer formation. Prednisone, a corticosteroid, increases the risk of gastric ulcer formation, especially with long-term use. While prednisone can also lead to hyperglycemia (choice A) and hypertension (choice B) as adverse effects, monitoring for gastric ulcer formation is a priority due to its association with corticosteroid therapy. Diarrhea (choice D) is not a common adverse effect of prednisone and is less likely compared to gastric ulcers.

Correct Answer: D

Rationale: The correct intervention when a client develops redness and warmth at the IV site, indicating phlebitis, is to discontinue the IV and notify the provider. This is crucial to prevent further complications. Elevating the IV site and applying an ice pack (Choice A) may not address the underlying issue of phlebitis. Administering an anti-inflammatory medication (Choice B) is not the primary intervention for phlebitis. Applying a cold compress (Choice C) may provide temporary relief but does not address the need to discontinue the IV when phlebitis occurs.

Correct Answer: A

Rationale: The correct answer is A: Monitor gastric residual volume and check for abdominal distension. These assessments are critical to evaluate the patient's tolerance to enteral feeding. Monitoring gastric residual volume helps determine gastric emptying, while checking for abdominal distension can identify complications like bowel obstruction. Choices B, C, and D are important aspects of enteral feeding care but are not the primary assessments. Ensuring the correct placement of the feeding tube is crucial for safety, assessing for signs of dehydration and electrolyte imbalances is essential for overall patient well-being, and elevating the head of the bed is vital to prevent aspiration. However, these are not the key assessments specifically related to enteral feeding.

Correct Answer: C

Rationale: After a bronchoscopy, the nurse's priority is to check for a gag reflex. This action helps assess the client's ability to protect their airway after sedation. Maintaining airway patency is crucial post-procedure. Monitoring oxygen levels is important but ensuring airway protection takes precedence. Encouraging the client to eat and administering IV fluids are essential aspects of care but are not the immediate priority in this situation.

Correct Answer: C

Rationale: Administering 4 oz of orange juice is the appropriate action for a client experiencing hypoglycemia due to diabetes mellitus. Orange juice contains simple sugars that can quickly raise blood glucose levels. Insulin (Choice A) would further lower blood sugar, worsening the condition. Glucagon (Choice B) is used in severe hypoglycemia when the client cannot take anything by mouth. Administering 1 L of water (Choice D) is not indicated in hypoglycemia treatment; the priority is to raise blood sugar levels. Therefore, the correct choice is to administer orange juice to address the low blood sugar in this situation.
