Nursing Elites

1. The nurse is caring for a client on mechanical ventilation. When performing endotracheal suctioning, the nurse will avoid hypoxia by

• A. Inserting a fenestrated catheter with a whistle tip without suction
• B. Completing the suction pass in 30 seconds with a pressure of 150 mm Hg
• C. Hyperoxygenating with 100% O2 for 1 to 2 minutes before and after each suction pass
• D. Minimizing the suction pass to 60 seconds while slowly rotating the lubricated catheter

Correct answer: C

Rationale: Hyperoxygenating the client before and after suctioning helps prevent hypoxia by ensuring adequate oxygen levels during the procedure, which briefly interrupts the client's normal breathing pattern. Choice A is incorrect because inserting a fenestrated catheter with a whistle tip without suction would not prevent hypoxia. Choice B is incorrect as completing the suction pass in 30 seconds with a pressure of 150 mm Hg may lead to hypoxia. Choice D is incorrect as minimizing the suction pass to 60 seconds may not provide enough time for effective suctioning and could lead to hypoxia.

2. The healthcare provider is evaluating the health status of a 16-year-old client with a history of Type 1 diabetes. Which laboratory test would provide the most accurate information about long-term blood glucose control?

• A. Blood glucose level
• B. Glycosylated hemoglobin
• C. Urine ketones
• D. Serum insulin level

Correct answer: B

Rationale: The correct answer is B: Glycosylated hemoglobin (HbA1c). Glycosylated hemoglobin provides valuable information about blood glucose control over the past 2-3 months. This test measures the average blood sugar levels during this period, offering a more comprehensive view of long-term glycemic control. Choice A, blood glucose level, reflects the blood sugar concentration at the time of testing and may fluctuate throughout the day. Choice C, urine ketones, indicates the presence of ketones and is more relevant for assessing acute complications like diabetic ketoacidosis. Choice D, serum insulin level, evaluates insulin production and is not a direct indicator of long-term blood glucose control in diabetes management.

3. The nurse is teaching a client with cardiac disease about the anatomy and physiology of the heart. Which is the correct pathway of blood flow through the heart?

• A. Right ventricle, left ventricle, right atrium, left atrium
• B. Left ventricle, right ventricle, left atrium, right atrium
• C. Right atrium, right ventricle, left atrium, left ventricle
• D. Right atrium, left atrium, right ventricle, left ventricle

Correct answer: C

Rationale: The correct pathway of blood flow through the heart starts with blood entering the right atrium, moving to the right ventricle, then to the lungs for oxygenation, returning to the left atrium, and finally to the left ventricle before being pumped out to the body. Option A is incorrect as it starts with the ventricles instead of the atria. Option B is incorrect as it has the sequence of ventricles before atria reversed. Option D is incorrect as it has the atria and ventricles mixed up.

4. A nurse is practicing community health nursing when:

• A. leading a support group for obese adolescents
• B. visiting an old woman in her condominium to change her postsurgical dressing
• C. being in a clinic instructing a couple about newborn care
• D. performing any of these activities

Correct answer: D

Rationale: Correct! Community health nursing involves a broad scope of activities that focus on promoting and preserving the health of populations rather than individuals. This includes leading support groups, providing home care, and educating communities. The other options represent different aspects of nursing care such as home health nursing, wound care, and maternal-child health - which are not exclusive to community health nursing.

5. The nurse is assessing a client with portal hypertension. Which of the following findings would the nurse expect?

• A. Expiratory wheezes
• B. Blurred vision
• C. Ascites
• D. Dilated pupils

Correct answer: C

Rationale: Ascites is a common finding in clients with portal hypertension. Portal hypertension results in increased pressure in the portal vein, leading to the development of ascites, which is the accumulation of fluid in the abdominal cavity. Expiratory wheezes (Choice A) are associated with respiratory conditions. Blurred vision (Choice B) is more commonly linked to eye disorders or neurological issues. Dilated pupils (Choice D) can be related to neurological conditions or drug effects, but not specifically to portal hypertension.
