Which of the following is not an indication for pelvic ultrasonography?

Correct Answer: C

Rationale: Pelvic ultrasonography is commonly used to assess various conditions. Choices A, B, and D are all valid reasons for performing pelvic ultrasonography. Measuring uterine size helps evaluate conditions like fibroids, while detecting multiple pregnancies is essential for prenatal care. Furthermore, identifying foreign bodies can aid in diagnosing certain conditions. However, assessing renal size is typically not a primary reason for pelvic ultrasonography, making choice C the correct answer.

Correct Answer: B

Rationale: Guillain-Barré syndrome is characterized by a severe complication of respiratory failure due to the involvement of the peripheral nerves that control breathing. While Bell's palsy, trigeminal neuralgia, and tetanus are also conditions affecting peripheral nerves, they do not typically lead to respiratory failure like Guillain-Barré syndrome. Bell's palsy causes facial muscle weakness, trigeminal neuralgia results in severe facial pain, and tetanus leads to muscle stiffness and spasms, but none of these conditions directly involve respiratory failure.

Correct Answer: C

Rationale: In cases of adenocarcinoma of the rectum with positive peritoneal lymph nodes, the most likely site of metastasis is the liver. Colon tumors commonly spread through the lymphatics and portal vein to the liver. While metastasis to the brain, bone, or mediastinum is possible, the liver is typically the first to be affected due to the anatomical pathways involved in colorectal cancer metastasis. Therefore, the correct answer is the liver. Metastasis to the brain, bone, or mediastinum would be less likely at this stage of colorectal cancer progression.

Correct Answer: A

Rationale: A small amount of bubbling is a normal finding in the water seal of a pleural drainage system when a client coughs. It is only a problem to find continuous, excessive bubbling in the water seal, which indicates a leak. Checking the system for leaks would be appropriate if there is continuous, excessive bubbling. Clamping the chest tube or changing the drainage system is not necessary in response to a small amount of bubbling during a cough, as this is considered a normal finding.

Correct Answer: D

Rationale: After ensuring the client's safety from the faulty electric bed, the nurse should prioritize preparing an incident report. This report documents the details of what happened and is crucial for quality improvement and risk management. Choice A, discussing the matter with the client's significant others, may be important in some cases but is not the immediate priority after a safety incident. Choice B, documenting the incident in the client's record, is necessary but should be preceded by preparing an incident report. Choice C, notifying the physician, is important but not as urgent as preparing the incident report to ensure timely reporting and investigation of the safety issue.

Correct Answer: D

Rationale: The recommended way to secure an infant in a car is to place them in the middle of the back seat in a rear-facing infant safety seat. Option A is incorrect because infants should never be held while in a moving vehicle due to safety concerns. Option B is incorrect because placing an infant in the front seat with a rear-facing safety seat can be risky if the car has passenger-side airbags. Option C is incorrect as booster seats are not suitable for infants. Therefore, the correct choice is to secure the infant in the middle of the back seat in a rear-facing infant safety seat.

Correct Answer: B

Rationale: Celiac disease, also known as celiac sprue, is a malabsorption disorder affecting the small intestine due to a problem with ingesting gluten, a protein found in wheat, rye, oats, and barley. Therefore, oats or barley cereal would present a problem for a client with Celiac Disease as they contain gluten. Fresh vegetables, butter, coffee, and tea, on the other hand, do not contain gluten and should not pose any issues for individuals with this disorder. Therefore, the correct answer is oats or barley cereal. Choices A, C, and D are not problematic for clients with Celiac Disease as they are gluten-free.

Correct Answer: B

Rationale: The correct answer is 'a client suspected of varicella (chickenpox).' Chickenpox is an acute, infectious airborne illness that requires airborne precautions, including wearing a respirator mask for direct contact with the patient. Choices A, C, and D do not typically require airborne precautions. Choice A describes symptoms that may indicate a gastrointestinal infection but do not require airborne precautions. Choice C mentions abdominal pain and purpura, which are not specific to an airborne illness. Choice D, a client diagnosed with AIDS, does not necessitate airborne precautions unless there are additional infectious conditions present that require such measures.

Correct Answer: D

Rationale: Amylase is elevated in conditions of pancreatic inflammation, such as pancreatitis. Pancreatitis is characterized by the inflammation of the pancreas, leading to the leakage of amylase into the bloodstream. Elevated levels of amylase are a key diagnostic marker for pancreatitis. Alkaline phosphatase is associated with liver and bone conditions, not pancreatitis. Acid phosphatase is more related to prostate health and is not specific to pancreatitis. Creatine phosphokinase is found in tissues like muscle and brain, and elevated levels are seen in conditions like muscle injury or heart attack, not pancreatitis.
