You have just received change-of-shift report about these patients on the coronary care step-down unit. Which patient will you assess first?

A. Keep the client NPO after midnight: Fasting is not required for a standard ECG. The procedure is noninvasive, quick, and does not involve sedation or contrast, so keeping the client NPO is unnecessary and does not impact the quality of the ECG recording.

B. Wash the skin with plain water before placing the electrodes: To ensure a clean signal and prevent "artifact" (electrical interference), the skin should be cleaned with soap and water or alcohol prep pads to remove body oils and dead skin cells.

C. Administer an analgesic prior to the procedure: ECG placement is painless, so analgesics are not needed. Administering medication unnecessarily could expose the client to side effects without benefit and is not standard practice.

D. Instruct the client not to talk during the test: Talking or moving during the ECG can create artifacts on the tracing that may obscure the rhythm, particularly in atrial fibrillation. Instructing the client to remain still and quiet helps ensure a clear, interpretable recording.

E. Inspect the electrode pads: Checking the electrode pads for damage, dryness, or expiration ensures proper adhesion and conductivity. Faulty electrodes can produce poor-quality tracings and lead to misinterpretation of the cardiac rhythm.

A. Nitroglycerine and Viagra should be taken at the same time: Taking nitroglycerine and Viagra together is extremely dangerous. Both drugs cause vasodilation and can lead to severe hypotension, syncope, or even cardiovascular collapse. Patients must be explicitly warned against simultaneous use.

B. Viagra is not effective when used in combination with nitroglycerine: The issue is not the efficacy of Viagra but the risk of life-threatening hypotension when the two medications are combined. Effectiveness of Viagra is not the concern; safety is the priority.

C. Viagra should not be used within 24 hours of taking nitroglycerine: The safest practice is to avoid nitrates for at least 24 hours after taking sildenafil (Viagra) due to the risk of profound hypotension. This instruction directly addresses patient safety and is a critical point for discharge teaching to prevent potentially fatal interactions.

D. The effect of nitroglycerine is impaired by concurrent use of Viagra: Nitroglycerine’s effectiveness is not impaired; instead, the combination potentiates vasodilation, leading to dangerously low blood pressure. The concern is additive hypotensive effects, not reduced efficacy of nitroglycerine.
