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. When replacing a client's surgical dressing, what should the nurse do?

• A. Don sterile gloves to remove the old dressing
• B. Wash hands thoroughly before removing the old dressing
• C. Use sterile gloves to remove the old dressing
• D. Apply a new dressing before removing the old one

Correct answer: C

Rationale: When replacing a client's surgical dressing, the nurse should use sterile gloves to remove the old dressing. Sterile technique is essential to prevent introducing infection to the wound. Choice A is incorrect because clean gloves are not sufficient; sterile gloves are necessary to maintain asepsis. Choice B, washing hands, is an important step before and after the procedure to maintain hand hygiene, but sterile gloves are required during the dressing change. Choice D is incorrect because a new dressing should only be applied after the old one has been removed to prevent contamination and ensure proper wound care.

3. What is the most important assessment for the LPN/LVN to perform on a client with a history of chronic obstructive pulmonary disease (COPD) receiving oxygen therapy at 2 liters per minute via nasal cannula?

• A. Assess the client's respiratory rate and effort.
• B. Measure the client's oxygen saturation level.
• C. Monitor the client's arterial blood gas levels.
• D. Check the client's blood pressure.

Correct answer: B

Rationale: Measuring the client's oxygen saturation level is the most important assessment in this scenario. Oxygen saturation level reflects how well the client is oxygenating, which is crucial in assessing the effectiveness of oxygen therapy for a client with COPD. Monitoring the respiratory rate and effort (Choice A) is important but assessing oxygenation with saturation levels takes precedence. While arterial blood gas levels (Choice C) provide comprehensive information, checking oxygen saturation is a quicker and more immediate way to assess oxygenation status. Checking blood pressure (Choice D) is not the priority when evaluating the effectiveness of oxygen therapy in COPD.

4. The nurse is preparing to provide a complete bed bath to an unconscious patient. The nurse decides to use a bag bath. In which order will the nurse clean the body, starting with the first area?

• A. Neck, shoulders, and chest
• B. Abdomen and groin/perineum
• C. Legs, feet, and web spaces
• D. Back of neck, back, and then buttocks

Correct answer: B

Rationale: In providing a complete bed bath using a bag bath for an unconscious patient, the nurse should follow a specific order. The correct sequence is as follows: Neck, shoulders, and chest; Both arms, both hands, web spaces, and axilla; Abdomen and then groin/perineum; Right leg, right foot, and web spaces; Left leg, left foot, and web spaces; Back of neck, back, and then buttocks. Choice A is incorrect as it does not follow the correct sequence for a bed bath. Choice C is incorrect as it focuses on the lower extremities before addressing the upper body. Choice D is incorrect as it starts with the back of the patient instead of the upper body areas first.

5. During auscultation of a client experiencing chest pain worsened by inspiration, a nurse hears a high-pitched scratching sound in both systole and diastole with the diaphragm of the stethoscope placed at the left sternal border. Which of the following heart sounds should the nurse document?

• A. Pericardial friction rub
• B. Murmur
• C. S1 and S2
• D. Bruit

Correct answer: A

Rationale: The correct answer is 'Pericardial friction rub.' A pericardial friction rub is a high-pitched, scratching sound heard in both systole and diastole, which is characteristic of pericardial inflammation. This sound is different from a murmur, which is a swooshing or blowing sound due to turbulent blood flow. S1 and S2 are normal heart sounds, and a bruit is a whooshing sound caused by turbulent blood flow in an artery, not related to pericardial inflammation.
