Nursing Elites

1. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?

• A. Blood glucose of 350 mg/dL
• B. Serum bicarbonate of 18 mEq/L
• C. Arterial pH of 7.20
• D. Serum potassium of 5.5 mEq/L

Correct answer: C

Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.

2. A client requires gastric decompression, and a nurse is inserting an NG tube. Which action should the nurse take to verify proper placement of the tube?

• A. Assess the client for a gag reflex
• B. Measure the pH of the gastric aspirate
• C. Place the end of the NG tube in water to observe for bubbling
• D. Auscultate 2.5 cm (1 in) above the umbilicus while injecting 15 mL of sterile water

Correct answer: B

Rationale: Measuring the pH of the gastric aspirate is the most reliable method to confirm proper placement of an NG tube. Gastric fluid has an acidic pH, typically ranging from 1 to 5. Assessing the client for a gag reflex (choice A) is important for airway protection but does not confirm tube placement. Placing the NG tube in water to observe for bubbling (choice C) is incorrect and not a reliable method for verifying placement. Auscultating 2.5 cm above the umbilicus while injecting sterile water (choice D) is an outdated method and is not recommended for verifying NG tube placement.

3. Which assessment data reflects the need for nurses to include the problem, “Risk for falls,” in a client’s plan of care?

• A. Recent serum hemoglobin level of 16 g/dL
• B. Opioid analgesic received one hour ago
• C. Stooped posture with an unsteady gait
• D. Expressed feelings of depression

Correct answer: B

Rationale: The correct answer is B. The recent administration of opioid analgesics increases the risk for falls due to potential side effects such as sedation and dizziness. Choice A, a recent serum hemoglobin level of 16 g/dL, is not directly related to the risk for falls. Choice C, stooped posture with an unsteady gait, may indicate an existing risk but does not directly reflect the need to include 'Risk for falls' in the care plan. Choice D, expressed feelings of depression, is important to address but is not directly associated with the risk for falls.

4. At the surgical scrub sink, a surgical nurse demonstrated the proper surgical handwashing technique by scrubbing:

• A. With her hands held lower than her elbows
• B. With her hands held higher than her elbows
• C. With her hands in a fist position
• D. With hands placed on her chest

Correct answer: B

Rationale: The correct technique for surgical handwashing involves scrubbing with hands held higher than the elbows. This positioning helps prevent water from the contaminated area (the hands) from flowing towards the cleaner area (the elbows). This directional flow minimizes the risk of contaminating the scrubbed hands during the handwashing process. Choices A, C, and D are incorrect: A - having hands lower than elbows would risk contamination of the clean area, C - using a fist position does not ensure proper coverage and thorough handwashing, and D - placing hands on the chest is not part of the proper surgical handwashing technique.

5. A nurse is preparing to administer enoxaparin subcutaneously. Which of the following actions should the nurse take?

• A. Administer the medication with the needle at a 45-degree angle.
• B. Administer the medication with the needle at a 90-degree angle.
• C. Administer the medication with the needle at a 30-degree angle.
• D. Administer the medication with the needle at a 15-degree angle.

Correct answer: B

Rationale: Enoxaparin should be administered with the needle at a 90-degree angle to ensure proper subcutaneous delivery. Choice B is correct as it aligns with the recommended angle for subcutaneous injections. Administering enoxaparin at a 45-degree angle (Choice A), 30-degree angle (Choice C), or 15-degree angle (Choice D) would not be appropriate and may lead to improper administration or absorption of the medication.
