The nurse includes the problem of “Risk for infection” in the plan of care for a client with myelosuppression. Which laboratory value provides the greatest support for this nursing problem?

Reference Range: Hemoglobin (Hgb) [14 to 18 g/dL (8.69 to 11.17 mmol/L)], Hematocrit (Hct) [42% to 52% (0.42 to 0.52 volume fraction)], Red Blood Cell Count (RBC) [4.2 to 5.4 x 10⁶/µL (4.2 to 5.4 x 10¹²/L)], White Blood Cell (WBC) [5,000 to 10,000/mm³ (5 to 10 x 10⁹/L)].

Red blood cell count of 3.5 x 10⁶/µL (3.5 x 10¹²/L).

White blood cell count of 1,500/mm³ (1.5 x 10⁹/L).

Hematocrit of 33% (0.33 volume fraction).

Hemoglobin of 10 g/dL (6.21 mmol/L).

Answer and Explanation

The Correct Answer is B

Choice A reason: A red blood cell count of 3.5 x 10⁶/µL indicates anemia from myelosuppression, reducing oxygen transport. RBCs do not fight infection, so this does not support “risk for infection.” Low WBCs impair immune defense, increasing infection susceptibility, making WBC count more relevant to the nursing problem in this context.

Choice B reason: A WBC count of 1,500/mm³ indicates severe leukopenia from myelosuppression, reducing neutrophil production. This impairs immune response, significantly raising infection risk, as pathogens overwhelm the body’s defenses. This lab value directly supports “risk for infection,” necessitating precautions like isolation or antibiotics to prevent opportunistic infections.

Choice C reason: Hematocrit of 33% reflects anemia in myelosuppression, lowering oxygen delivery. This causes fatigue but does not increase infection risk, as RBCs are not immune cells. WBCs, particularly neutrophils, are critical for infection defense, making low WBC count more relevant to the nursing problem than hematocrit.

Choice D reason: Hemoglobin of 10 g/dL indicates anemia, reducing oxygen-carrying capacity in myelosuppression. This does not directly increase infection risk, as hemoglobin is not involved in immunity. Low WBCs compromise pathogen defense, making WBC count the key value supporting “risk for infection” in this client’s care plan.

Correct Answer is C

Explanation

Choice A reason: Monitoring the metabolic panel detects antibiotic side effects like renal toxicity, but this is ongoing. Collecting blood cultures first identifies the HAP pathogen, ensuring targeted therapy. Premature antibiotics may obscure results, leading to resistance, making cultures more urgent for effective treatment of this nosocomial infection.

Choice B reason: Nebulizer treatments aid airway clearance in HAP, but identifying the pathogen via cultures is critical before antibiotics. Ineffective therapy delays recovery, as bacteria proliferate in mucus. Cultures guide precise antibiotic selection, reducing resistance risk, making this less immediate than obtaining microbiological data.

Choice C reason: Collecting blood cultures before antibiotics identifies the HAP pathogen (e.g., MRSA) and its sensitivity, critical for tailoring therapy. Broad-spectrum antibiotics can yield false-negative cultures, complicating treatment. This ensures accurate diagnosis, optimizing outcomes in severe infections, addressing the microbiological basis of HAP management.

Choice D reason: Reviewing chest x-ray confirms HAP with infiltrates but does not guide immediate antibiotic therapy. Cultures are urgent to identify the pathogen before antibiotics, as x-rays are non-specific and already documented. Cultures ensure pathogen-specific treatment, critical for combating hospital-acquired infections effectively.

A. Evaluate amount of urinary output hourly. B. Clamp the catheter for 5 minutes hourly. C. Secure the ureteral catheter to the client’s leg. D. Report urine leakage around ureteral catheter.

Correct Answer is D

Explanation

Choice A reason: Evaluating urinary output hourly monitors renal function post-ureterolithotomy, as obstruction or complications may reduce output. However, urine leakage around the catheter suggests dislodgement or ureteral injury, risking peritonitis or infection. Reporting leakage is more urgent, as it indicates a critical catheter malfunction requiring immediate medical attention.

Choice B reason: Clamping the ureteral catheter risks obstructing urine flow, increasing pressure and causing ureteral damage or reflux, potentially leading to hydronephrosis or infection. Leakage around the catheter is a more pressing issue, indicating possible perforation or displacement, necessitating urgent reporting to prevent severe complications.

Choice C reason: Securing the catheter prevents dislodgement but is routine. Urine leakage suggests a critical issue like catheter malfunction or ureteral injury, which could cause peritonitis or fistula. Reporting leakage takes precedence, as it addresses a potentially life-threatening complication, ensuring timely intervention over standard catheter care.

Choice D reason: Reporting urine leakage is critical, as it may indicate catheter displacement or ureteral perforation, risking peritonitis or infection. Leakage suggests the catheter fails to drain urine properly, a serious post-surgical issue requiring immediate assessment, potentially via imaging or surgical correction, to prevent renal or systemic complications.
