Correct Answer: D

Rationale: The correct answer is 'Hemoglobin.' Hemoglobin levels are not indicative of coagulation status but are important for assessing oxygen-carrying capacity. Choices A, B, and C are all laboratory tests that assess coagulation. Partial thromboplastin time (PTT) and prothrombin time (PT) evaluate different aspects of the coagulation cascade, while platelet count is essential for assessing primary hemostasis. Therefore, in the context of evaluating coagulation, hemoglobin is not the appropriate choice.

Correct Answer: D

Rationale: A CT scan is most likely to be performed in this scenario. A CT scan would be done to further investigate the cause of the left hemiparesis. Noncontrast CT scanning is commonly used in the acute evaluation of patients with suspected acute stroke to assess for ischemic changes or hemorrhage in the brain. While a CBC may provide information on blood cell counts and general health status, it is not the primary test for evaluating hemiparesis. An ECG is used to assess heart function and rhythm, which is not the main concern in this case. Thyroid function tests evaluate thyroid hormone levels and are not typically the initial tests for evaluating hemiparesis and confusion.

Correct Answer: D

Rationale: The correct answer is 'Generalized edema.' Acute glomerulonephritis typically presents with periorbital edema, not generalized edema. Findings in acute glomerulonephritis include dark, smoky, or tea-colored urine (hematuria) due to red blood cells in the urine, elevated blood pressure, and proteinuria. The urine specific gravity may be high due to decreased urine output, but a urine output of 350 ml in 24 hours is extremely low and suggestive of renal impairment. Generalized edema is more commonly associated with nephrotic syndrome, where there is significant proteinuria leading to hypoalbuminemia and subsequent fluid retention in tissues. In acute glomerulonephritis, the edema is usually limited to the face and lower extremities, not generalized.

Correct Answer: D

Rationale: The correct answer is Aspirin. Aspirin is not known to cause urine discoloration. Sulfasalazine is associated with causing orange-yellow discoloration of urine. Levodopa can cause darkening of urine to a brown or black color. Phenolphthalein has been linked to pink or red discoloration of urine. Therefore, among the options provided, Aspirin is the medication least likely to cause urine discoloration.

Correct Answer: B

Rationale: A client experiencing an anaphylactic reaction will likely present with rash or hives, swelling of the lips, face, or tongue, hypotension, or dyspnea. In this scenario, the client is showing signs of anaphylaxis with dyspnea, chest tightness, hives, hypotension, and swelling of the lips and tongue. The next appropriate action would be to administer 0.3 mg of 1:1000 epinephrine intramuscularly. Epinephrine helps relax the muscles of the airway, improve breathing, and increase oxygenation, which is crucial in managing anaphylaxis. Starting an IV and administering fluids can be important but not the immediate priority. Diphenhydramine may be used as an adjunct therapy but should not delay the administration of epinephrine in the acute phase of anaphylaxis. Monitoring the client without providing immediate treatment can lead to a worsening of the anaphylactic reaction, potentially resulting in a life-threatening situation.
