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.

A nurse on a medical-surgical unit is washing her hands prior to assisting with a surgical procedure. Which of the following actions by the nurse demonstrates proper surgical hand-washing technique?
- A. The nurse washes with her hands held higher than her elbows.
- B. The nurse uses an alcohol-based hand rub for 30 seconds.
- C. The nurse scrubs hands and forearms for 2 minutes with soap and water.
- D. The nurse washes her hands with soap and water for only 15 seconds.
Correct Answer: A
Rationale: Proper surgical hand-washing technique involves washing with the hands held higher than the elbows. This positioning is essential to ensure proper rinsing and to prevent the risk of contamination. Option B, using an alcohol-based hand rub for 30 seconds, is not specific to surgical hand-washing and is more commonly used for routine hand hygiene. Option C, scrubbing hands and forearms for 2 minutes with soap and water, is excessive and not typically required for routine hand-washing. Option D, washing hands with soap and water for only 15 seconds, is insufficient for thorough surgical hand-washing.
A nurse on a medical-surgical unit is receiving a change-of-shift report for four clients. Which of the following clients should the nurse see first?
- A. A client who has new onset of dyspnea 24 hours after a total hip arthroplasty
- B. A client who has acute abdominal pain rated 4 on a scale from 0 to 10
- C. A client who has a UTI and low-grade fever
- D. A client who has pneumonia and an oxygen saturation of 96%
Correct Answer: A
Rationale: The nurse should prioritize seeing the client who has new onset dyspnea 24 hours after a total hip arthroplasty first. This sudden dyspnea could indicate a serious complication like a pulmonary embolism, which requires immediate assessment and intervention. Acute abdominal pain, a UTI with a low-grade fever, and pneumonia with an oxygen saturation of 96% are important concerns but are not as immediately life-threatening as potential pulmonary embolism indicated by sudden dyspnea postoperatively.
The nurse is preparing to administer a subcutaneous injection of enoxaparin (Lovenox). Which site is most appropriate for the LPN/LVN to use?
- A. Deltoid muscle
- B. Ventrogluteal site
- C. Abdomen
- D. Dorsogluteal site
Correct Answer: C
Rationale: The abdomen is the most appropriate site for administering subcutaneous injections of enoxaparin (Lovenox). Enoxaparin is typically administered in the abdomen due to better absorption and reduced risk of injury to underlying structures. The deltoid muscle is not recommended for subcutaneous injections of enoxaparin due to the potential risk of injury to underlying structures. The ventrogluteal and dorsogluteal sites are more appropriate for intramuscular injections rather than subcutaneous injections.
A nurse is admitting a client who has an abdominal wound with a large amount of purulent drainage. Which of the following types of transmission precautions should the nurse initiate?
- A. Protective environment
- B. Airborne precautions
- C. Droplet precautions
- D. Contact precautions
Correct Answer: D
Rationale: The correct answer is D: Contact precautions. When a client has an abdominal wound with purulent drainage, contact precautions are necessary to prevent the spread of infection through direct contact. Protective environment precautions are used for immunocompromised clients, airborne precautions are for diseases transmitted by airborne particles, and droplet precautions are for diseases transmitted by respiratory droplets. In this case, the focus is on preventing direct contact transmission, making contact precautions the most appropriate choice. Protective environment, airborne, and droplet precautions are not indicated in this scenario because the primary concern is the direct contact transmission of pathogens through the wound drainage.
A nurse manager is assigning care of a client who is being admitted from the PACU following thoracic surgery. The nurse manager should assign the client to which of the following staff members?
- A. Charge nurse
- B. Registered nurse (RN)
- C. Practical nurse (PN)
- D. Assistive personnel (AP)
Correct Answer: B
Rationale: In this scenario, a client who has undergone thoracic surgery and is being admitted from the PACU requires a high level of nursing care. Registered nurses (RNs) have the education and training necessary to provide the complex care and monitoring needed for a post-thoracic surgery client. Charge nurses may oversee units but may not always be directly involved in providing bedside care. Practical nurses (PNs) have a different scope of practice compared to RNs and may not have the advanced skills needed for post-thoracic surgery care. Assistive personnel (AP) provide valuable support but do not have the qualifications to manage the care of a client following thoracic surgery.
