The nurse is assessing a client who is admitted to the renal unit with suspected decreased renal perfusion. The nurse should plan to carefully monitor which parameter?
Reference Range: Urine white blood cells (WBC) [0 to 4 WBC/low powered field (lpf)]

Choice A reason: Obtaining another blood pressure measurement is critical, as lethargy, pallor, and diaphoresis suggest hypotension or shock, despite the earlier 140/90 reading. This guides safe administration of antihypertensives, preventing harm, per cardiovascular assessment and medication safety protocols in nursing practice.

Choice B reason: Determining recent medications is important but secondary to assessing current blood pressure, as symptoms suggest acute instability. Blood pressure confirms hypotension risk before reviewing drugs, ensuring timely intervention, per cardiovascular assessment and patient safety standards in nursing care.

Choice C reason: Administering antihypertensives without reassessing blood pressure is unsafe, as lethargy, pallor, and diaphoresis indicate possible hypotension. Confirming blood pressure prevents exacerbating instability, per medication safety and cardiovascular monitoring protocols in nursing practice for clients with hypertension.

Choice D reason: Consulting the PN about the 0800 condition delays immediate assessment of current symptoms. Blood pressure measurement addresses acute lethargy, pallor, and diaphoresis, guiding intervention. Consultation is secondary, per prioritization and cardiovascular assessment standards in nursing care.

Choice A reason: Keeping pressure on the abdomen and coughing is incorrect for diaphragmatic breathing, which enhances lung expansion, not airway clearance. Coughing is for post-drainage. The client’s incorrect technique (abdominal expansion on exhalation) requires correction, as this reverses mechanics, reducing ventilation efficiency in conditions like COPD.

Choice B reason: The client’s technique is incorrect, expanding the abdomen on exhalation, not inhalation, reducing diaphragmatic efficacy. Confirming it as correct is wrong, as it impairs lung expansion. Demonstrating proper technique corrects the error, ensuring effective breathing to improve oxygenation, addressing the physiological need for ventilation.

Choice C reason: Documenting success is inaccurate, as the client’s technique is reversed, expanding the abdomen on exhalation. Diaphragmatic breathing requires inhalation expansion to lower the diaphragm, increasing lung capacity. Correcting the technique via demonstration ensures proper mechanics, not documenting an ineffective method that hinders ventilation.

Choice D reason: Demonstrating proper diaphragmatic breathing corrects the client’s error of exhalation expansion. Inhaling expands the abdomen via diaphragmatic descent, increasing tidal volume; exhaling relaxes it. This optimizes ventilation, addressing the need for effective breathing in conditions requiring enhanced lung function, ensuring the client learns the correct technique.
