A 62-year-old male client with a history of coronary artery disease complains that his heart is 'racing' and he often feels dizzy. His blood pressure is 110/60, and he uses portable oxygen at 2 liters per nasal cannula. Based on the rhythm shown, which prescription should the nurse administer?
- A. Give magnesium via secondary infusion.
- B. Initiate IV heparin solution as per protocol.
- C. Administer IV adenosine (Adenocard).
- D. Prepare for synchronized cardioversion.
Correct Answer: C
Rationale: The correct answer is C: Administer IV adenosine (Adenocard).
Rationale:
1. The ECG rhythm shows regular narrow complex tachycardia, likely supraventricular tachycardia (SVT).
2. Adenosine is the first-line medication for terminating SVT by blocking conduction through the AV node.
3. Adenosine is given rapidly as a bolus dose followed by a saline flush to ensure quick delivery to the heart.
4. Adenosine has a very short half-life, making it safe to use in this scenario.
Summary:
A: Magnesium is not the first-line treatment for SVT.
B: Heparin is not indicated for the management of SVT.
D: Synchronized cardioversion is reserved for unstable patients with hemodynamic compromise, not indicated for stable SVT.

The healthcare provider is planning care for a non-potty-trained child with nephrotic syndrome. Which intervention provides the best means of determining fluid retention?
- A. Weigh the child daily.
- B. Observe the lower extremities for pitting edema.
- C. Measure the child's abdominal girth weekly.
- D. Weigh the child's wet diapers.
Correct Answer: A
Rationale: The correct answer is A: Weigh the child daily. Daily weight monitoring is the most accurate way to determine fluid retention in a child with nephrotic syndrome as it provides real-time data on fluid status. Weight gain is a key indicator of fluid retention in these patients. Observing lower extremities for pitting edema (B) is subjective and may not accurately reflect fluid status. Measuring abdominal girth weekly (C) may not provide timely information on fluid retention. Weighing wet diapers (D) does not give a comprehensive picture of total fluid retention and may not be as accurate as daily weight monitoring.
Which assessment finding indicates a client's readiness to leave the nursing unit for a bronchoscopy?
- A. Client denies allergies to contrast media.
- B. Skin prep to insertion site completed.
- C. On-call sedation administered.
- D. Oxygen at 2 L/minute via nasal cannula.
Correct Answer: C
Rationale: Rationale: Option C, on-call sedation administered, is the correct answer because sedation is essential for bronchoscopy to ensure the client is comfortable and cooperative during the procedure. Sedation helps reduce anxiety and discomfort, making the procedure more tolerable. Options A, B, and D are incorrect as they do not directly indicate readiness for the procedure. Denying allergies to contrast media (A) is important but not specific to bronchoscopy readiness. Skin prep completion (B) is part of the pre-procedure preparation but does not confirm readiness. Oxygen administration (D) is a routine care measure and does not indicate readiness for bronchoscopy.
The client has acute kidney injury (AKI). Which assessment finding requires immediate intervention?
- A. Urine output of 50 ml in the last hour.
- B. Serum potassium of 6.2 mEq/L.
- C. Blood pressure of 150/90 mm Hg.
- D. Serum creatinine of 2.5 mg/dL.
Correct Answer: B
Rationale: The correct answer is B: Serum potassium of 6.2 mEq/L. Hyperkalemia is a life-threatening condition in AKI. High potassium levels can lead to cardiac arrhythmias and must be addressed immediately. Choice A is concerning but not as critical as hyperkalemia. Choice C, elevated blood pressure, needs monitoring but does not require immediate intervention. Choice D, elevated serum creatinine, indicates kidney dysfunction but does not pose an immediate threat compared to hyperkalemia.
An elderly client with congestive heart failure (CHF) is admitted to the hospital. Which laboratory test result should the nurse expect to find?
- A. Elevated serum sodium level.
- B. Decreased brain natriuretic peptide (BNP) level.
- C. Increased serum creatinine level.
- D. Elevated hemoglobin and hematocrit levels.
Correct Answer: C
Rationale: The correct answer is C, increased serum creatinine level. In CHF, the heart's reduced pumping ability can lead to decreased blood flow to the kidneys, resulting in impaired kidney function. This can cause an elevation in serum creatinine level, indicating decreased kidney function. Elevated serum sodium level (A) is not typically seen in CHF, as patients often have fluid retention leading to dilutional hyponatremia. Decreased BNP level (B) is not expected in CHF, as BNP is released in response to increased ventricular stretching and volume overload. Elevated hemoglobin and hematocrit levels (D) are not directly related to CHF; they may be seen in conditions like dehydration or chronic hypoxia, but not specifically in CHF.
The client with chronic kidney disease (CKD) is receiving hemodialysis. Which finding should be reported to the healthcare provider immediately?
- A. Blood pressure of 150/90 mm Hg.
- B. Weight gain of 2 pounds since the last dialysis session.
- C. Blood glucose level of 120 mg/dl.
- D. Potassium level of 6.5 mEq/L.
Correct Answer: D
Rationale: The correct answer is D: Potassium level of 6.5 mEq/L. High potassium levels (hyperkalemia) in CKD patients receiving hemodialysis can lead to serious complications like cardiac arrhythmias or even cardiac arrest. Therefore, it is crucial to report this finding immediately to the healthcare provider for prompt intervention.
Explanation for other choices:
A: Blood pressure of 150/90 mm Hg - While elevated, this blood pressure reading is not an immediate concern unless accompanied by symptoms like chest pain or shortness of breath.
B: Weight gain of 2 pounds since the last dialysis session - While weight gain may indicate fluid retention, it is not an urgent issue unless it is rapid and significant.
C: Blood glucose level of 120 mg/dl - A blood glucose level of 120 mg/dl is within the normal range and does not require immediate action in this context.
