Nursing Elites

1. A public health nurse is addressing the issue of childhood lead poisoning in a low-income community. Which intervention should be prioritized?

• A. Providing free blood lead level testing for children
• B. Distributing pamphlets on the dangers of lead exposure
• C. Conducting home inspections for lead-based paint
• D. Educating parents about lead poisoning prevention

Correct answer: A

Rationale: Providing free blood lead level testing for children should be prioritized as it directly identifies children who are at risk and in need of intervention. This intervention allows for early detection and timely implementation of necessary measures to prevent further lead exposure or address existing poisoning. Distributing pamphlets (choice B) may raise awareness but does not directly identify at-risk children. Conducting home inspections (choice C) is important but may not be as immediate and targeted as blood lead level testing. Educating parents (choice D) is essential but may not directly identify and address individual cases of lead poisoning as testing does.

2. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

3. The client with liver cirrhosis needs immediate intervention for which abnormal laboratory result?

• A. Prothrombin time (PT) of 14 seconds.
• B. Bilirubin of 1.2 mg/dL.
• C. Albumin of 4 g/dL.
• D. Ammonia level of 80 mcg/dL.

Correct answer: D

Rationale: An elevated ammonia level of 80 mcg/dL indicates hepatic encephalopathy, a serious complication of liver cirrhosis that requires immediate intervention. Ammonia is a neurotoxin that accumulates in the blood due to impaired liver function, leading to cognitive impairment and altered mental status. Monitoring and lowering ammonia levels are crucial in managing hepatic encephalopathy to prevent further neurological deterioration. Prothrombin time, bilirubin, and albumin levels are important parameters in assessing liver function and overall health status in clients with liver cirrhosis, but an elevated ammonia level poses an immediate threat to neurological function and warrants prompt attention.

4. The healthcare provider is preparing to administer intravenous immune globulin (IVIG) to a client with Guillain-Barre syndrome. Which assessment is most important before initiating the infusion?

• A. Lung sounds and respiratory status.
• B. Skin integrity and color.
• C. Neurological status and level of consciousness.
• D. Cardiac rate and rhythm.

Correct answer: D

Rationale: The correct answer is D, "Cardiac rate and rhythm." Monitoring cardiac rate and rhythm is crucial before initiating IVIG because bradycardia is a common side effect associated with this therapy. Assessing lung sounds and respiratory status (Choice A) is important, but cardiac monitoring takes precedence due to the risk of bradycardia. Skin integrity and color (Choice B) are important assessments, but they are not directly related to potential complications of IVIG infusion. Neurological status and level of consciousness (Choice C) are also vital assessments, but monitoring cardiac function is more pertinent in this scenario.

5. The nurse is assessing a client who complains of weight loss, racing heart rate, and difficulty sleeping. The nurse determines the client has moist skin with fine hair, prominent eyes, lid retraction, and a staring expression. These findings are consistent with which disorder?

• A. Graves' disease.
• B. Cushing's syndrome.
• C. Addison's disease.
• D. Hypothyroidism.

Correct answer: A

Rationale: The correct answer is A, Graves' disease. The symptoms described in the client are classic manifestations of hyperthyroidism, which is commonly caused by Graves' disease, an autoimmune condition affecting the thyroid. Weight loss, racing heart rate, difficulty sleeping, moist skin with fine hair, prominent eyes, lid retraction, and a staring expression are all indicative of hyperthyroidism. Choice B, Cushing's syndrome, is characterized by weight gain, hypertension, and a rounded face due to excess cortisol. Choice C, Addison's disease, presents with symptoms such as weight loss, fatigue, and hyperpigmentation due to adrenal insufficiency. Choice D, hypothyroidism, typically features symptoms opposite to those described in the client, such as weight gain, bradycardia, and dry skin.
