Nursing Elites

1. Following a lumbar puncture, a client complains of worsening headache when sitting up. What complication is the client likely experiencing?

• A. A migraine headache
• B. An infection from the puncture site
• C. Low blood sugar
• D. Spinal fluid leakage (post-lumbar puncture headache)

Correct answer: D

Rationale: The client is likely experiencing spinal fluid leakage (post-lumbar puncture headache), a common complication of a lumbar puncture. This leakage results in a reduction of cerebrospinal fluid volume around the brain and spinal cord, leading to a headache that worsens when in an upright position due to reduced buoyancy. A migraine headache (Choice A) is not typically associated with a lumbar puncture. Infection from the puncture site (Choice B) would present with localized signs of inflammation, such as redness, swelling, and warmth, rather than worsening headache. Low blood sugar (Choice C) is not a common complication of lumbar puncture and would not typically manifest as a worsening headache when sitting up.

2. A client with chronic liver disease is prescribed lactulose. Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?

• A. Bilirubin level
• B. Serum ammonia level
• C. Serum potassium level
• D. Albumin level

Correct answer: B

Rationale: The correct answer is B: Serum ammonia level. Lactulose is used to lower serum ammonia levels in clients with chronic liver disease, particularly in cases of hepatic encephalopathy. Monitoring serum ammonia levels is crucial to evaluate the effectiveness of lactulose in managing hepatic encephalopathy. Choices A, C, and D are incorrect because they are not directly related to the action or evaluation of lactulose in chronic liver disease.

3. An older client is admitted to the intensive care unit unconscious after several days of vomiting and diarrhea. The nurse inserts a urinary catheter and observes dark amber urine output. Which intervention should the nurse implement first?

• A. Begin dopamine infusion at 2 mcg/kg/minute.
• B. Begin potassium chloride 10 mEq over 1 hour.
• C. Give a bolus of 0.9% sodium chloride 1000 mL over 30 minutes.
• D. Administer promethazine 25 mg IV push.

Correct answer: C

Rationale: In this scenario, the priority intervention is to give a bolus of 0.9% sodium chloride 1000 mL over 30 minutes. The client's dark amber urine output indicates dehydration and hypovolemia, requiring rapid fluid resuscitation. Dopamine infusion, potassium chloride, and promethazine are not the initial interventions needed for a client with hypovolemic symptoms.

4. A client with cirrhosis is at risk for bleeding due to impaired liver function. Which laboratory result is the most important to monitor?

• A. Blood urea nitrogen (BUN)
• B. Prothrombin time (PT)
• C. Aspartate aminotransferase (AST)
• D. Serum albumin

Correct answer: B

Rationale: Prothrombin time (PT) measures the time it takes for blood to clot and is a critical indicator of bleeding risk in clients with liver dysfunction. Impaired liver function reduces clotting factor production, leading to an increased PT, which requires close monitoring. Monitoring BUN (Choice A) is more indicative of kidney function, not clotting ability. Aspartate aminotransferase (AST) (Choice C) and serum albumin (Choice D) are important indicators of liver function, but they do not directly assess the client's bleeding risk.

5. What instruction should the nurse include for a client prescribed nitroglycerin for a myocardial infarction?

• A. Take the medication only when experiencing severe chest pain.
• B. Store the medication in a dark container to protect it from light.
• C. Take the medication before engaging in physical activity that may trigger chest pain.
• D. Limit nitroglycerin use to no more than three doses in 15 minutes.

Correct answer: D

Rationale: The correct answer is D: 'Limit nitroglycerin use to no more than three doses in 15 minutes.' This instruction is crucial to prevent excessive use, which can lead to severe hypotension and other complications. Choice A is incorrect because nitroglycerin should also be used preventatively, not only during severe chest pain. Choice B is irrelevant and not a necessary instruction for nitroglycerin use. Choice C is incorrect as nitroglycerin is typically taken to prevent chest pain rather than waiting for an activity that may trigger it.
