When planning care for a 16-year-old with appendicitis presenting with right lower quadrant pain, what should the nurse prioritize as a nursing diagnosis?

A. Imbalanced nutrition: Less than body requirements related to decreased oral intake

B. Risk for infection related to possible rupture of the appendix

C. Constipation related to decreased bowel motility and decreased fluid intake

D. Chronic pain related to appendicitis

Correct Answer: B
Rationale: The priority nursing diagnosis for a client with appendicitis is the 'Risk for infection related to possible rupture of the appendix.' Appendicitis carries a risk of the appendix rupturing, which can lead to peritonitis, a life-threatening condition. Preventing infection through timely intervention and surgery is critical in the care of a client with appendicitis, making this nursing diagnosis the priority.

What instruction should be provided to a client with a history of myocardial infarction (MI) who is prescribed nitroglycerin?

• A. Take nitroglycerin with food to avoid stomach upset.
• B. Store nitroglycerin tablets in a dark, glass container.
• C. Swallow nitroglycerin tablets whole without chewing.
• D. Discontinue the medication if a headache occurs.

Correct Answer: B
Rationale: Nitroglycerin is a medication that should be stored in a dark, glass container to protect it from light and moisture. Exposure to light and moisture can reduce its effectiveness. Storing it in a dark, glass container helps maintain the medication's stability and potency, ensuring that it remains safe and effective for use in emergencies, such as angina attacks.

What instruction should the nurse include in the discharge teaching for a patient with hypothyroidism prescribed levothyroxine?

• A. Take the medication with meals.
• B. Take the medication in the morning on an empty stomach.
• C. Discontinue the medication if you feel better.
• D. Double the dose if a dose is missed.

Correct Answer: B
Rationale: The correct instruction for a patient with hypothyroidism prescribed levothyroxine is to take the medication in the morning on an empty stomach to enhance absorption. Taking it with meals can interfere with absorption. Patients should not discontinue the medication without consulting their healthcare provider as it can lead to adverse effects. Doubling the dose if a dose is missed can increase the risk of side effects and overdosage. It is crucial for patients to follow the prescribed dosing schedule and consult their healthcare provider for any concerns or missed doses.

A client who is receiving heparin therapy has an activated partial thromboplastin time (aPTT) of 90 seconds. What action should the nurse take?

• A. Increase the heparin infusion rate.
• B. Notify the healthcare provider.
• C. Apply pressure to the injection site.
• D. Administer protamine sulfate.

Correct Answer: B
Rationale: An activated partial thromboplastin time (aPTT) of 90 seconds is elevated, indicating a risk of bleeding. The appropriate action for the nurse is to notify the healthcare provider. Increasing the heparin infusion rate can further elevate the aPTT, leading to an increased risk of bleeding. Applying pressure to the injection site is not relevant in this situation. Administering protamine sulfate is used to reverse the effects of heparin in cases of overdose or bleeding, but it is not the initial action for an elevated aPTT.

A client is admitted with diabetic ketoacidosis (DKA). Which assessment finding requires immediate intervention?

• A. Fruity breath odor.
• B. Blood glucose of 450 mg/dL.
• C. Deep, rapid respirations.
• D. Serum potassium of 5.2 mEq/L.

Correct Answer: C
Rationale: The correct answer is C: Deep, rapid respirations (Kussmaul breathing). This is a sign of severe acidosis commonly seen in diabetic ketoacidosis (DKA) and requires immediate intervention. Kussmaul breathing helps to compensate for the metabolic acidosis by blowing off carbon dioxide. Prompt intervention is necessary to prevent further deterioration and potential respiratory failure. Fruity breath odor (Choice A) is a classic sign of DKA but does not require immediate intervention. While a blood glucose level of 450 mg/dL (Choice B) is high, it does not pose an immediate threat to the client's life. Serum potassium of 5.2 mEq/L (Choice D) is slightly elevated but not the most critical finding that requires immediate intervention in this scenario.
