A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?
- A. Hemoglobin of 11 g/dl
- B. Platelet count of 150,000
- C. INR of 2.5
- D. Potassium of 2.7 mEq/L
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.

To detect possible complications in a patient with severe cirrhosis who has bleeding esophageal varices, it is most important for the nurse to monitor
- A. bilirubin levels.
- B. ammonia levels.
- C. potassium levels.
- D. prothrombin time.
Correct Answer: B
Rationale: In a patient with severe cirrhosis and bleeding esophageal varices, monitoring ammonia levels is crucial. Severe liver dysfunction impairs the metabolism of protein in the GI tract, leading to increased ammonia levels. Elevated ammonia levels can result in hepatic encephalopathy, a serious complication. Monitoring bilirubin levels is important for assessing liver function and jaundice but may not directly reflect the risk of complications from bleeding esophageal varices. Potassium levels are important but not the most critical in this scenario. Prothrombin time is essential for evaluating coagulation status but does not directly relate to the risk of complications from bleeding esophageal varices in this patient.
A 30-year-old woman is experiencing anaphylaxis from a bee sting. Emergency personnel have been called. The nurse notes the woman is breathing but short of breath. Which of the following interventions should the nurse do first?
- A. Initiate cardiopulmonary resuscitation
- B. Check for a pulse
- C. Ask the woman if she carries an emergency medical kit
- D. Stay with the woman until help comes
Correct Answer: C
Rationale: In a situation where a patient is experiencing anaphylaxis, it is crucial to act swiftly. Asking the woman if she carries an emergency medical kit is the most appropriate initial intervention. Many individuals with a history of anaphylaxis carry epinephrine auto-injectors, such as epi-pens, which can be life-saving in such situations. Initiating cardiopulmonary resuscitation (CPR) is not indicated as the patient is breathing but short of breath, and CPR is not the first-line intervention for anaphylaxis. Checking for a pulse, though important, is not the initial priority in managing anaphylaxis. Staying with the woman until help arrives is essential for providing support and monitoring her condition, but confirming the availability of an emergency medical kit takes precedence to promptly address the anaphylactic reaction.
Following a diagnosis of acute glomerulonephritis (AGN) in their 6-year-old child, the parent's remark: "We just don't know how he caught the disease!"? The nurse's response is based on an understanding that:
- A. AGN is a streptococcal infection that involves the kidney tubules.
- B. The disease is easily transmissible in schools and camps.
- C. The illness is usually associated with chronic respiratory infections.
- D. It is not "caught"? but is a response to a previous B-hemolytic strep infection.
Correct Answer: D
Rationale: The correct answer is that acute glomerulonephritis (AGN) is not 'caught' but is a response to a previous B-hemolytic strep infection. AGN is generally accepted as an immune-complex disease triggered by an antecedent streptococcal infection occurring 4 to 6 weeks prior. It is considered a noninfectious renal disease. Choice A is incorrect because AGN is not a streptococcal infection that involves the kidney tubules but rather a noninfectious renal disease. Choice B is incorrect as AGN is not easily transmissible in schools and camps but is a result of a previous streptococcal infection. Choice C is incorrect as AGN is not usually associated with chronic respiratory infections, but with a previous streptococcal infection.
A 67-year-old male patient with acute pancreatitis has a nasogastric (NG) tube to suction and is NPO. Which information obtained by the nurse indicates that these therapies have been effective?
- A. Bowel sounds are present.
- B. Grey Turner sign resolves.
- C. Electrolyte levels are normal.
- D. Abdominal pain is decreased.
Correct Answer: D
Rationale: The correct answer is 'Abdominal pain is decreased.' In a patient with acute pancreatitis, the goal of using an NG tube for suction and keeping the patient NPO is to decrease the release of pancreatic enzymes and alleviate pain. Therefore, a decrease in abdominal pain would indicate the effectiveness of these therapies. Bowel sounds being present do not necessarily indicate treatment effectiveness, as they can still be present even if the therapies are not fully effective. Normal electrolyte levels are important but do not directly reflect the efficacy of NG suction and NPO status. The resolution of Grey Turner sign, a bruising over the flanks associated with pancreatitis, is a late and non-specific finding and waiting for it to resolve is not a reliable indicator of treatment effectiveness.
A 3-year-old had a hip spica cast applied 2 hours ago. In order to facilitate drying, the nurse should:
- A. Expose the cast to air and turn the child frequently.
- B. Use a heat lamp to reduce the drying time.
- C. Handle the cast with the abductor bar.
- D. Turn the child as little as possible.
Correct Answer: A
Rationale: After a hip spica cast is applied, it is important to facilitate drying by exposing the cast to air and turning the child frequently, approximately every 2 hours. This helps ensure even drying and prevents skin breakdown. Using a heat lamp can cause burns and should be avoided. Handling the cast with the abductor bar is not necessary for the drying process and may cause discomfort to the child. Turning the child as little as possible is not recommended as regular turning helps prevent complications like pressure ulcers and stiffness.
