1. Which lab test is used to assess renal function?

A. Check blood glucose levels
B. Monitor serum creatinine
C. Monitor BUN
D. Check electrolyte levels

Correct answer: B

Rationale: The correct answer is B: Monitor serum creatinine. Serum creatinine is a key indicator of renal function as it reflects the glomerular filtration rate. An increase in serum creatinine levels indicates impaired kidney function. Checking blood glucose levels (choice A) is not specific to assessing renal function but is used to diagnose diabetes. Monitoring BUN (choice C) is important but not as specific as serum creatinine in assessing renal function. Checking electrolyte levels (choice D) is essential in assessing kidney function but is not as specific as monitoring serum creatinine.

2. Which medication is used to reverse the effects of opioid overdose?

A. Naloxone
B. Epinephrine
C. Atropine
D. Lidocaine

Correct answer: A

Rationale: Naloxone is the correct answer. Naloxone is specifically used to reverse the effects of opioid overdose by binding to opioid receptors and blocking the effects of opioids. Epinephrine is mainly used to treat severe allergic reactions, Atropine is used for certain types of heart conditions and to reduce salivation or respiratory secretions, and Lidocaine is a local anesthetic used for numbing purposes. Therefore, choices B, C, and D are incorrect in the context of reversing opioid overdose.

3. A client who is 14 weeks of gestation reports swelling of the face. What should the nurse do next?

A. Administer an analgesic.
B. Report this finding to the provider immediately.
C. Administer an antiemetic.
D. Monitor the client's vital signs.

Correct answer: B

Rationale: The correct answer is to report this finding to the provider immediately. Swelling of the face in pregnancy can be a sign of preeclampsia, a serious condition characterized by high blood pressure and signs of damage to another organ system, often the kidneys. Prompt reporting and intervention are crucial to prevent complications for both the client and the fetus. Administering an analgesic (choice A) is not appropriate for this situation as it does not address the underlying cause of the swelling. Administering an antiemetic (choice C) is used to treat nausea and vomiting, which are not the primary concerns associated with facial swelling in this scenario. Monitoring the client's vital signs (choice D) is important but should be done after reporting the finding to the provider to guide further assessment and management.

4. In an emergency department following a community disaster, a healthcare provider is performing triage for multiple clients. To which of the following types of injuries should the provider assign the highest priority?

A. Below-the-knee amputation.
B. Fractured tibia.
C. 95% full-thickness body burn.
D. 10 cm laceration to the forearm.

Correct answer: A

Rationale: During disaster triage, clients with severe injuries that are immediately life-threatening and have a high likelihood of mortality without intervention are assigned the highest priority. A below-the-knee amputation falls into this category as it indicates a critical injury that requires immediate attention to prevent further complications or loss of life. Fractured tibia, a 95% full-thickness body burn, and a 10 cm laceration to the forearm, while serious, do not pose the same level of immediate life-threatening risk as a below-the-knee amputation in the context of disaster triage.

5. A nurse is caring for a client who has cirrhosis. Which of the following findings should the nurse expect?

A. Decreased bilirubin levels
B. Decreased prothrombin time
C. Decreased albumin levels
D. Increased prothrombin time

Correct answer: D

Rationale: In clients with cirrhosis, the liver is unable to produce clotting factors efficiently, leading to impaired clotting function. Therefore, an increased prothrombin time is expected in cirrhosis. Choices A, B, and C are incorrect. Decreased bilirubin levels are not typically seen in cirrhosis; prothrombin time is usually increased, not decreased; and albumin levels are often decreased in cirrhosis due to reduced synthetic liver function.
