NCLEX RN Exam Questions - Nurselytic

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.

Correct Answer: B

Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations.
Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.

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.

Correct Answer: A

Rationale: The priority intervention in this scenario is to start a large-bore IV in the patient's arm. The patient's low blood pressure (95/60) and elevated pulse rate (110 beats per minute) indicate a potential hemorrhage, requiring immediate fluid resuscitation. Starting a large-bore IV will allow for rapid administration of fluids to stabilize the patient's condition. Asking for a stool sample, preparing to insert an NG tube, or administering morphine sulfate should not take precedence over addressing the hemodynamic instability and potential hemorrhage observed in the patient. These actions may be considered later in the patient's care, but the primary focus should be on addressing the critical issue of fluid replacement and stabilization.

Correct Answer: B

Rationale: A positive urine pregnancy test would require an immediate change in the therapeutic plan for a patient with grade 2 hepatic encephalopathy due to the teratogenic effects of ribavirin. Ribavirin needs to be discontinued immediately to prevent harm to the fetus. The other options, weight loss, hemoglobin level, and complaints of nausea and anorexia, are common adverse effects of the prescribed regimen and may necessitate interventions such as patient education or supportive care, but they would not mandate an immediate cessation of therapy as in the case of a positive pregnancy test.
