Which of the following best describes a somatic symptom disorder?

Correct Answer: C

Rationale: The correct answer is C. Somatic symptom disorder is characterized by individuals having excessive preoccupation with physical symptoms that may or may not have an identifiable medical cause. Choice A is incorrect because the sudden onset of symptoms due to stress is more indicative of acute stress reaction. Choice B is incorrect as it describes physical manifestations related to known medical conditions, not somatic symptom disorder. Choice D is incorrect as it relates to health anxiety or illness anxiety disorder, where individuals avoid seeking medical care due to fear of receiving a diagnosis.

Correct Answer: C

Rationale: The correct answer is C: 'Avoid lifting more than 10 lb.' After a cataract extraction, the nurse should instruct the client to avoid lifting heavy objects to prevent increased intraocular pressure, which could lead to complications. Choices A, B, and D are incorrect. A - 'Bend at the waist when picking up objects' can increase intraocular pressure; B - 'Avoid lying on the operative side' is not a specific concern related to cataract extraction; D - 'Apply ice to the affected eye' is not a standard post-cataract extraction instruction.

Correct Answer: B

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient presenting with chest pain as it helps dilate blood vessels, reduce chest pain, and improve oxygen supply to the heart. Obtaining a detailed medical history, conducting an ECG, or administering morphine sulfate are important steps in the assessment and treatment process but are secondary to the immediate need to address chest pain and potential cardiac ischemia.

Correct Answer: D

Rationale: Elevated BUN levels are a characteristic finding in dehydration due to reduced kidney perfusion and increased reabsorption of urea. Hemoglobin levels might be elevated in conditions like polycythemia vera, not directly related to dehydration. A low sodium level could be seen in conditions like hyponatremia. A high white blood cell count is more indicative of infection or inflammation rather than dehydration.

Correct Answer: C

Rationale: The correct answer is C: 'Increases cough production.' Guaifenesin is an expectorant that works by increasing cough production to help clear secretions from the airways. Option A is incorrect because guaifenesin does not decrease mucus production but rather helps to make the mucus easier to cough up. Option B is incorrect as guaifenesin does not reduce nasal congestion. Option D is incorrect because guaifenesin does not have any effect on reducing fever.
