A 24-year-old female contracts hepatitis from contaminated food. During the acute (icteric) phase of the patient's illness, what would serologic testing most likely reveal?
- A. antibody to hepatitis D (anti-HDV).
- B. hepatitis B surface antigen (HBsAg).
- C. anti-hepatitis A virus immunoglobulin G (anti-HAV IgG).
- D. anti-hepatitis A virus immunoglobulin M (anti-HAV IgM).
Correct Answer: D
Rationale: Hepatitis A is primarily transmitted through the oral-fecal route. During the acute phase of hepatitis A, serologic testing typically reveals anti-hepatitis A virus immunoglobulin M (anti-HAV IgM). This antibody appears early in the course of the infection. The presence of anti-HAV IgM indicates an acute infection with hepatitis A. Choices A and B are incorrect as hepatitis D and hepatitis B antigens are not typically associated with acute hepatitis A. Choice C, anti-hepatitis A virus immunoglobulin G (anti-HAV IgG), would indicate a past infection and lifelong immunity, which is not expected during the acute phase of the illness.

While receiving normal saline infusions to treat a GI bleed, the nurse notes that the patient's lower legs have become edematous and auscultates crackles in the lungs. What should the nurse do first?
- A. Stop the saline infusion immediately
- B. Notify the physician
- C. Elevate the patient's legs
- D. Continue the infusion, as these findings are normal
Correct Answer: A
Rationale: The correct answer is to stop the saline infusion immediately. The patient is showing signs of fluid volume overload due to rapid fluid replacement, indicated by lower leg edema and lung crackles. Continuing the infusion could worsen the overload and potentially lead to complications. Notifying the physician is important but should come after stopping the infusion to address the immediate issue. Elevating the patient's legs may help with edema but is not the priority in this situation. Continuing the infusion when the patient is already showing signs of fluid overload is contraindicated and can be harmful.
The nurse is working in a support group for clients with HIV. Which point is most important for the nurse to stress?
- A. They must inform household members of their condition.
- B. They must take their medications exactly as prescribed.
- C. They must abstain from substance use.
- D. They must avoid large crowds.
Correct Answer: B
Rationale: The correct answer is that clients with HIV must take their medications exactly as prescribed. Antiretrovirals need to be taken as directed to prevent the development of drug-resistant strains and maintain treatment effectiveness. Missing doses can compromise the effectiveness of future treatments. Choice A, informing household members, is important for social support but not the most critical aspect of managing the condition. Choice C, abstaining from substance use, is important but not as crucial as medication adherence. Choice D, avoiding large crowds, is not directly related to HIV management as long as the individual's immune system is not significantly compromised.
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.
Which action will be included in the care for a patient who has recently been diagnosed with asymptomatic nonalcoholic fatty liver disease (NAFLD)?
- A. Teach about symptoms of variceal bleeding
- B. Draw blood for hepatitis serology testing
- C. Discuss the need to increase caloric intake
- D. Review the patient's current medication list
Correct Answer: D
Rationale: The correct action for a patient diagnosed with asymptomatic nonalcoholic fatty liver disease (NAFLD) would be to review the patient's current medication list. This is important because certain medications can increase the risk for NAFLD, and they should be identified and possibly eliminated. Teaching about symptoms of variceal bleeding is not necessary as variceal bleeding is not a concern in a patient with asymptomatic NAFLD. Drawing blood for hepatitis serology testing is not indicated as NAFLD is not associated with hepatitis. Discussing the need to increase caloric intake is also not appropriate since weight loss is usually recommended in the management of NAFLD.
A newborn has been diagnosed with hypothyroidism. In discussing the condition and treatment with the family, the nurse should emphasize:
- A. They can expect the child will be mentally retarded.
- B. Administration of thyroid hormone will prevent problems.
- C. This rare problem is always hereditary.
- D. Physical growth/development will be delayed.
Correct Answer: B
Rationale: The correct answer is administration of thyroid hormone will prevent problems. In newborns diagnosed with hypothyroidism, early identification and continuous treatment with hormone replacement can correct this condition effectively. Choice A is incorrect as it uses outdated and inappropriate language (mentally retarded) and does not reflect modern understanding of conditions. Choice C is incorrect because while some cases of hypothyroidism can be hereditary, it is not always the case. Choice D is incorrect as physical growth and development can be affected by hypothyroidism, but the critical emphasis should be on the importance of administering thyroid hormone to prevent complications and support normal growth and development.
