A nurse is caring for a client who has a new prescription for metformin. Which of the following laboratory results should the nurse evaluate prior to administering the first dose?
Potassium level
Creatinine level
Platelet count
Liver enzymes
The Correct Answer is B
Before administering the first dose of metformin, the nurse should evaluate the client's creatinine level. Metformin is primarily excreted by the kidneys, and its clearance from the body depends on the renal function. If the client has impaired kidney function, metformin can accumulate in the body and lead to potential adverse effects, particularly lactic acidosis.
Monitoring the creatinine level helps assess the client's kidney function and determines whether it is safe to administer metformin. If the creatinine level is elevated, indicating reduced kidney function, the nurse should consult with the healthcare provider to determine the appropriate dose adjustment or consider an alternative treatment option.
Let's go through the other options and explain why they are not the priority laboratory results to evaluate before administering metformin:
A. Potassium level: While monitoring potassium levels is important in some situations, it is not a primary concern before administering metformin. Metformin does not have a significant effect on potassium levels, and it is not a medication known for causing hypokalemia (low potassium levels).
C. Platelet count: Metformin does not have a direct impact on platelet count, and evaluating platelet count is not typically required before starting metformin therapy. Platelet count monitoring may be relevant for certain other medications or medical conditions, but it is not specific to metformin administration.
D. Liver enzymes: While it is essential to monitor liver function in clients on long-term metformin therapy, evaluating liver enzymes before the first dose of metformin is not the priority. Metformin is primarily cleared by the kidneys, and liver enzymes are not directly affected by its initial administration. However, ongoing monitoring of liver function may be necessary during long-term

Correct Answer is D
Explanation
A. Intake and output: Monitoring intake and output is essential in the postoperative care of a client to assess fluid balance and kidney function. However, it is not the priority assessment when the client has received isoflurane in the PACU. The priority assessment in this situation is related to the potential cardiovascular side effect of isoflurane, which is hypotension. Hypotension can have immediate and significant implications for the client's perfusion and overall well-being, requiring prompt attention and intervention.
B. Non-verbal pain cues: Assessing for pain is important in the postoperative period to ensure adequate pain management and comfort for the client. However, it is not the priority assessment when the client has received isoflurane in the PACU. The priority assessment at this time is related to the potential cardiovascular impact of the anesthesia, which is blood pressure. Addressing hypotension takes precedence over pain assessment as it poses a more immediate threat to the client's well-being.
C. Bowel sounds: Assessing bowel sounds is part of a comprehensive postoperative assessment to monitor the return of bowel function after surgery. While it is important, it is not the priority assessment when the client has received isoflurane in the PACU. The priority assessment in this situation is related to the potential cardiovascular side effect of the anesthesia, which is blood pressure. Monitoring and managing hypotension is of greater concern in the immediate postoperative period.
D. Blood pressure: This is the correct answer. The priority assessment for a client who received isoflurane in the PACU is the blood pressure. Isoflurane is an inhalation anesthetic that can cause hypotension (low blood pressure). Monitoring the client's blood pressure is crucial to promptly identify and address any hypotension, as it can lead to inadequate tissue perfusion and oxygenation. Addressing blood pressure deviations is essential for the client's cardiovascular stability and overall recovery in the PACU.
Correct Answer is C
Explanation
The nurse should expect angioedema as one of the manifestations of anaphylaxis in a client experiencing an allergic reaction to an antibiotic. Angioedema is a severe swelling that occurs beneath the skin, typically affecting the face, lips, tongue, throat, or other body parts. It is a result of the release of histamine and other inflammatory mediators in response to the allergen.
Anaphylaxis is a life-threatening allergic reaction that can occur rapidly and affect multiple body systems. In addition to angioedema, other common manifestations of anaphylaxis include:
-
Difficulty breathing or wheezing due to bronchospasm
-
Hives or urticaria, which are itchy raised skin rashes
-
Severe itching or tingling sensation
-
Rapid and weak pulse
-
Low blood pressure leading to hypotension
-
Nausea, vomiting, or diarrhea
-
Feeling of impending doom or anxiety
Let's go through the other options:
A. Hypertonic reflexes: This is not a manifestation of anaphylaxis. "Hypertonic reflexes" are not typically associated with allergic reactions or anaphylaxis. Hypertonic reflexes refer to increased muscle tone, but they are not part of the usual presentation of anaphylaxis.
B. Increase in systolic blood pressure: Anaphylaxis usually leads to a decrease in blood pressure rather than an increase. The decrease in blood pressure can be severe and result in shock, which is a life-threatening condition.
D. Urinary retention: Urinary retention is not a common manifestation of anaphylaxis. Anaphylaxis primarily affects the respiratory and circulatory systems, leading to airway constriction, difficulty breathing, and cardiovascular collapse. Urinary retention is not directly related to the pathophysiology of anaphylaxis.
