Correct Answer: B

Rationale: The correct nursing action for a patient with balloon tamponade for bleeding esophageal varices is to monitor the patient for shortness of breath. The most common complication of balloon tamponade is aspiration pneumonia. Additionally, if the gastric balloon ruptures, the esophageal balloon may slip upward and occlude the airway. Instructing the patient to cough every hour is incorrect as coughing increases the pressure on the varices and raises the risk of bleeding. Verifying the position of the balloon every 4 hours is unnecessary as it is typically done after insertion. Deflating the gastric balloon if the patient reports nausea is incorrect because deflating it may cause the esophageal balloon to occlude the airway, leading to complications. Therefore, monitoring for signs of respiratory distress is crucial in this situation.

Correct Answer: B

Rationale: The nurse's first action should be to massage the fundus until it is firm as uterine atony is the primary cause of bleeding in the first hour after delivery. Massaging the fundus helps to stimulate uterine contractions, which can help control the bleeding. Checking vital signs would be important but addressing the primary cause of bleeding takes precedence. Offering a bedpan is not a priority in this situation as the focus should be on managing the postpartum bleeding. Checking for perineal lacerations is also important but not the initial action needed to address the boggy uterus and vaginal bleeding.

Correct Answer: D

Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.

Correct Answer: A

Rationale: The priority nursing diagnosis for a patient experiencing a migraine headache is 'Acute pain related to biologic and chemical factors.' Migraine headaches are characterized by severe throbbing pain, often accompanied by sensitivity to light and sound. Addressing the acute pain is crucial to improve the patient's comfort and quality of life. Choices B, C, and D are not the priority nursing diagnoses for a patient with a migraine headache. Anxiety, hopelessness, and risk for side effects may not be as urgent as managing the acute pain associated with a migraine.

Correct Answer: C

Rationale: The correct answer is to take pancrelipase (Viokase) with each meal. Pancrelipase is a pancreatic enzyme replacement medication that helps with the digestion of nutrients. Patients with chronic pancreatitis often have difficulty digesting food properly due to insufficient pancreatic enzyme production. Taking pancrelipase with each meal assists in the breakdown of fats, proteins, and carbohydrates consumed during the meal. Option A ('at bedtime') is incorrect because enzymes should be taken with meals to aid in digestion. Option B ('in the morning') is not ideal as it does not ensure optimal enzyme activity during meals. Option D ('for abdominal pain') is incorrect as pancrelipase is not meant to be taken solely for pain relief but rather to aid in digestion.
