A 3-year-old had a hip spica cast applied 2 hours ago. In order to facilitate drying, the nurse should:

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.

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.

Correct Answer: C

Rationale: The correct answer is the patient's temperature of 100.8°F (38.2°C). In a patient who received a liver transplant 1 week ago, a fever is a significant finding that should be promptly communicated to the health care provider. Post-transplant patients are at high risk of infections, and fever can often be the initial indicator of an underlying infectious process. The other findings listed in choices A, B, and D are important and should be addressed, but they do not take precedence over a potential infection post-liver transplant. Dry palpebral and oral mucosa may indicate dehydration, crackles at bilateral lung bases may suggest fluid overload or infection, and no bowel movement for 4 days could indicate a bowel obstruction or ileus. However, in the context of a recent liver transplant, an elevated temperature is the most concerning and requires immediate attention to rule out infection.

Correct Answer: C

Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.

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: 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.

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: 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: 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.
