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.

Which action should the nurse take to evaluate treatment effectiveness for a patient who has hepatic encephalopathy?
- A. Ask the patient to extend both arms forward.
- B. Request that the patient walk with eyes closed.
- C. Ask the patient to perform the Valsalva maneuver.
- D. Observe the patient's breathing pattern.
Correct Answer: B
Rationale: To evaluate treatment effectiveness for a patient with hepatic encephalopathy, requesting the patient to walk with eyes closed is crucial. This test assesses the patient's balance, gait, and coordination, which can be impaired in hepatic encephalopathy due to altered mental status and brain function. Walking with eyes closed challenges the patient's sensory input and proprioception, providing valuable information on improvement or deterioration in neurological function. Asking the patient to extend both arms forward is used to check for asterixis, a sign often seen in hepatic encephalopathy, but it is not specific for evaluating treatment effectiveness. Performing the Valsalva maneuver is unrelated to assessing hepatic encephalopathy and is more commonly used in cardiac evaluations. Observing the patient's breathing pattern may be important in other conditions but is not directly relevant to evaluating treatment effectiveness for hepatic encephalopathy.
The nurse is assessing an infant with developmental dysplasia of the hip. Which finding would the nurse anticipate?
- A. Unequal leg length
- B. Limited adduction
- C. Diminished femoral pulses
- D. Symmetrical gluteal folds
Correct Answer: A
Rationale: In developmental dysplasia of the hip (DDH), one of the key findings is unequal leg length. This occurs due to the dislocation of the hip joint, where the ball is loose in the socket. Limited adduction, the inability to bring the hip and knee towards the midline of the body, is also a common finding in DDH. Diminished femoral pulses are not typically associated with DDH, as it primarily affects the skeletal structure rather than vascular supply. Symmetrical gluteal folds are normal in infants and do not indicate DDH, as asymmetry in gluteal folds can be a sign of hip dislocation.
During a physical exam, a healthcare professional assisting a client suspected of having meningitis bends the client's leg at the hip to a 90-degree angle. When attempting to extend the leg at the knee, the client experiences severe pain. What type of test is being performed?
- A. Brudzinski's sign
- B. Romberg's sign
- C. Kernig's sign
- D. Babinski's sign
Correct Answer: C
Rationale: The healthcare professional is performing Kernig's sign, a test for meningeal irritation often seen in meningitis cases. Kernig's sign involves bending the client's leg at a 90-degree angle at the hip and then attempting to extend the leg at the knee. Severe pain during this maneuver indicates a positive Kernig's sign, suggesting irritation of the meningeal membranes. Brudzinski's sign involves flexing the neck causing involuntary flexion of the hips and knees; Romberg's sign assesses balance and proprioception; Babinski's sign checks for abnormal reflexes in the foot.
A 30-year-old man is being admitted to the hospital for elective knee surgery. Which assessment finding is most important to report to the healthcare provider?
- A. Tympany on percussion of the abdomen
- B. Liver edge 3 cm below the costal margin
- C. Bowel sounds of 20/minute in each quadrant
- D. Aortic pulsations visible in the epigastric area
Correct Answer: B
Rationale: The correct answer is 'Liver edge 3 cm below the costal margin.' Normally, the lower border of the liver is not palpable below the ribs, so this finding suggests hepatomegaly, which could indicate an underlying health issue. Tympany on percussion of the abdomen, bowel sounds of 20/minute in each quadrant, and aortic pulsations visible in the epigastric area are all within normal limits for a physical assessment and do not require immediate reporting to the healthcare provider.
A client is scheduled for an Intravenous Pyelogram (IVP). In order to prepare the client for this test, the nurse would:
- A. Instruct the client to maintain a regular diet the day prior to the examination.
- B. Restrict the client's fluid intake 4 hours prior to the examination.
- C. Administer a laxative to the client the evening before the examination.
- D. Inform the client that only 1 x-ray of his abdomen is necessary.
Correct Answer: C
Rationale: The correct preparation for an Intravenous Pyelogram (IVP) involves administering a laxative to the client the evening before the examination. This is crucial to ensure adequate bowel preparation, which in turn allows for better visualization of the bladder and ureters during the procedure. An IVP is an x-ray exam that utilizes contrast material to evaluate the kidneys, ureters, and bladder, aiding in the diagnosis of conditions like blood in the urine or pain in the side or lower back. Administering a laxative helps in achieving optimal imaging quality, which is essential for accurate diagnosis and subsequent treatment planning.
Choice A is incorrect because maintaining a regular diet is not the standard preparation for an IVP. Choice B is incorrect as fluid intake is not typically restricted for this procedure. Choice D is incorrect as an IVP involves multiple x-rays to assess the urinary system, not just one of the abdomen.
