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 A

Explanation

Choice A reason: Increased JVD and pedal edema indicate fluid overload in heart failure, where reduced cardiac output causes venous congestion. Assessing breathing for dyspnea or crackles detects pulmonary edema, as fluid backs into alveoli, impairing gas exchange. This urgent finding guides interventions like diuretics, critical before reporting.

Choice B reason: Palpating pedal pulses assesses arterial flow, not fluid overload causing JVD and edema, which are venous issues in heart failure. Pulses may be normal despite congestion. Breathing changes indicate pulmonary edema, a life-threatening complication, making this assessment more critical for detecting acute decompensation.

Choice C reason: Assessing calf inflammation may detect thrombosis, a heart failure risk, but JVD and edema suggest fluid overload, not clotting. Breathing changes are more urgent, indicating pulmonary edema from alveolar fluid, requiring immediate intervention to prevent respiratory failure, unlike inflammation, which is less immediate.

Choice D reason: Inspecting peripheral vein distention confirms venous congestion but is less critical than breathing assessment. In heart failure, fluid overload risks pulmonary edema, where alveolar fluid causes dyspnea. Monitoring breathing detects this severe complication, prioritizing intervention to ensure oxygenation over additional venous assessment.

A. Position the sterile field even with the nurse’s hips. B. Clean the urinary meatus before retracting the foreskin. C. Use a swab to wipe the meatus in backward strokes. D. Advance the catheter before inflating the balloon.

Correct Answer is B

Explanation

Choice A reason: Positioning the sterile field at hip level maintains sterility but is not specific to uncircumcised clients. Cleaning the meatus before retracting the foreskin prevents infection by removing bacteria first. This is secondary, per infection control and catheterization procedure standards in nursing practice.

Choice B reason: Cleaning the meatus before retracting the foreskin removes bacteria, reducing infection risk in uncircumcised clients. This sequence ensures sterility before exposing sensitive areas, critical for preventing urinary tract infections, per evidence-based catheterization and infection control protocols in urological nursing care.

Choice C reason: Wiping the meatus in backward strokes is incorrect, as circular strokes from meatus outward are standard to avoid contamination. Cleaning before retracting the foreskin is critical for infection prevention. This violates sterile technique, per catheterization and infection control standards in nursing.

Choice D reason: Advancing the catheter before inflating the balloon is standard but not specific to uncircumcised clients. Cleaning the meatus first addresses foreskin-related infection risks. Balloon inflation timing is universal, per indwelling catheter insertion and urological care protocols in nursing practice.
