Nursing Elites

1. A client is brought to the emergency department by a neighbor. The client is lethargic and has a fruity odor on the breath. The client’s arterial blood gas (ABG) results are pH 7.25, PCO2 34 mm Hg, PO2 86 mm Hg, HCO3 14 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: The correct answer is 'Metabolic acidosis.' Metabolic acidosis is characterized by a low pH (<7.35) and a low bicarbonate level (HCO3 <22 mEq/L). In this case, the client's ABG results show a pH of 7.25 and an HCO3 level of 14 mEq/L, indicating metabolic acidosis. The PCO2 of 34 mm Hg is normal, ruling out respiratory acidosis or alkalosis. The PO2 of 86 mm Hg is also within the normal range and is not indicative of a respiratory problem. Therefore, the client is experiencing metabolic acidosis based on the ABG results provided.

2. Which of the following indicates a potential complication of diabetes mellitus?

• A. Inflamed and painful joints.
• B. Blood pressure of 160/100 mm Hg.
• C. Stooped posture.
• D. Hemoglobin of 9 g/dL (90 g/L).

Correct answer: B

Rationale: A blood pressure of 160/100 mm Hg indicates hypertension, which is a common complication of diabetes mellitus due to atherosclerotic changes. Hypertension is a significant risk factor for cardiovascular diseases, which are prevalent in individuals with diabetes. Inflamed and painful joints (Choice A) are not directly related to diabetes complications but may be seen in conditions like arthritis. Stooped posture (Choice C) is more indicative of musculoskeletal issues like osteoporosis, not necessarily a typical complication of diabetes. Hemoglobin level of 9 g/dL (90 g/L) (Choice D) could signify anemia, which can occur in diabetes but is not a primary complication often associated with the disease.

3. A client with acute glomerulonephritis (GN) is being evaluated by a nurse. Which manifestation should the nurse recognize as a positive response to the prescribed treatment?

• A. The client has lost 11 pounds in the past 10 days.
• B. The client’s urine specific gravity is 1.048.
• C. No blood is observed in the client’s urine.
• D. The client’s blood pressure is 152/88 mm Hg.

Correct answer: A

Rationale: A weight loss of 11 pounds in the past 10 days indicates fluid loss, a positive response to treatment for acute glomerulonephritis. It signifies that the glomeruli are functioning adequately to filter excess fluid. A urine specific gravity of 1.048 is high, indicating concentrated urine, which is not a positive response in this context. Blood in the urine is not a typical finding in glomerulonephritis, so its absence is expected and does not indicate a positive response to treatment. A blood pressure of 152/88 mm Hg is elevated and may suggest kidney damage or fluid overload, which are not positive responses to treatment.

4. During CPR, when attempting to ventilate a client's lungs, the nurse notes that the chest is not moving. What action should the nurse take first?

• A. Use a laryngoscope to check for a foreign body lodged in the airway.
• B. Reposition the head to ensure that the airway is properly opened.
• C. Turn the client to the side and administer three back blows.
• D. Perform a finger sweep of the mouth to clear any obstructions.

Correct answer: B

Rationale: The most common reason for inadequate lung aeration during CPR is the incorrect positioning of the head, leading to airway obstruction. Therefore, the initial action should be to reposition the head to open the airway properly and attempt to ventilate again. Using a laryngoscope to check for foreign bodies in the airway (Choice A) is not the first step and could delay crucial interventions. Turning the client to the side and administering back blows (Choice C) is not indicated in this scenario as the focus is on ventilating the lungs. Performing a finger sweep of the mouth (Choice D) is not recommended as it may push obstructions further into the airway during CPR.

5. A client is tested for HIV with the use of an enzyme-linked immunosorbent assay (ELISA), and the test result is positive. The nurse should tell the client that:

• A. HIV infection has been confirmed
• B. The client probably has an opportunistic infection
• C. The test will need to be confirmed with the use of a Western blot
• D. A positive test is a normal result and does not mean that the client is infected with HIV

Correct answer: C

Rationale: When an ELISA test for HIV is positive, it is essential to confirm the result with a Western blot. The Western blot is the confirmatory test for HIV. Choice A is incorrect because a positive ELISA test does not confirm HIV infection. Choice B is incorrect as it assumes a different diagnosis. Choice D is incorrect because a positive ELISA test does indicate potential HIV infection and requires confirmation.
