Question 1 of 5
A nurse is caring for a client who is receiving an epidural infusion for pain management. Which assessment finding requires immediate intervention from the nurse?
Correct Answer: B
Rationale: The correct answer is B: Report of headache and stiff neck. This finding indicates a potential complication of epidural anesthesia called a post-dural puncture headache, which can lead to serious consequences like meningitis or subdural hematoma. The nurse should act immediately by notifying the healthcare provider for further evaluation and management. Redness at the catheter insertion site (
A) may indicate local inflammation but doesn't require immediate intervention. Temperature elevation (
C) could be a sign of infection but isn't as urgent as a headache and stiff neck. Pain rating of 8 (
D) is important but doesn't indicate an immediate threat to the client's health like a post-dural puncture headache.
Question 2 of 5
A client at risk for mild hypernatremia is being taught by a nurse. Which statement should the nurse include in this client's teaching?
Correct Answer: C
Rationale: The correct answer is C. Reading food labels to determine sodium content is important in managing mild hypernatremia. This allows the client to monitor and control their sodium intake, which can help prevent further elevation of sodium levels. Weighing oneself or checking the pulse does not directly address sodium intake. Choosing cooking methods like baking or grilling is more about reducing fat intake, not sodium.
Question 3 of 5
A nurse is assessing clients for fluid and electrolyte imbalances. Which client should the nurse assess first for potential hyponatremia?
Correct Answer: A
Rationale: The correct answer is A because intravenous D5W is a hypotonic solution that can lead to dilutional hyponatremia. D5W does not contain sodium, so it can cause a decrease in serum sodium levels. Clients on NPO status receiving D5W are at higher risk due to lack of sodium intake.
Choices B, C, and D are incorrect because they do not directly contribute to hyponatremia. Sulfonamide antibiotics, ibuprofen, and digoxin are not typically associated with causing hyponatremia.
Therefore, assessing the client on NPO status receiving D5W for potential hyponatremia is the priority.
Question 4 of 5
A gerontologic nurse is teaching students about the high incidence and prevalence of dehydration in older adults. What factors contribute to this phenomenon? Select all that do not apply.
Correct Answer: D
Rationale: The correct answer is D: Increased conservation of sodium. Older adults tend to have an increased conservation of sodium, leading to fluid retention and decreased fluid intake, which can contribute to dehydration.
A: Decreased kidney mass is incorrect because it is a factor that can contribute to decreased kidney function but not directly linked to dehydration.
B: Decreased renal blood flow can impact kidney function but is not a direct cause of dehydration in older adults.
C: Decreased excretion of potassium is not a factor that directly contributes to dehydration in older adults.
Question 5 of 5
While assessing a clients peripheral IV site, the nurse observes a streak of red along the vein path and palpates a 4-cm venous cord. How should the nurse document this finding?
Correct Answer: A
Rationale: The correct answer is A: Grade 3 phlebitis at IV site. This finding indicates inflammation of the vein due to irritants from the IV catheter, supported by red streak and palpable cord. Grade 3 phlebitis involves pain, redness, swelling, and palpable venous cord. Infection (
B) typically presents with signs like pus, warmth, and fever. Thrombosis (
C) involves a blood clot, not a palpable cord. Infiltration (
D) is leakage of IV fluid into surrounding tissues, not related to palpable cord and red streak.
