Correct Answer: B

Rationale: Furosemide (Lasix) is the correct answer. In a client with heart failure experiencing weight gain and peripheral edema, the priority is to manage fluid overload. Furosemide is a loop diuretic commonly prescribed to reduce excess fluid in heart failure patients. Lisinopril (Zestril) is an ACE inhibitor used to treat hypertension and heart failure but does not directly address fluid overload. Metoprolol (Lopressor) is a beta-blocker that helps manage heart failure symptoms but does not primarily target fluid retention. Simvastatin (Zocor) is a statin used to lower cholesterol levels and is not indicated for managing fluid overload in heart failure.

Correct Answer: A

Rationale: Proper surgical hand-washing technique involves washing with the hands held higher than the elbows. This positioning is essential to ensure proper rinsing and to prevent the risk of contamination. Option B, using an alcohol-based hand rub for 30 seconds, is not specific to surgical hand-washing and is more commonly used for routine hand hygiene. Option C, scrubbing hands and forearms for 2 minutes with soap and water, is excessive and not typically required for routine hand-washing. Option D, washing hands with soap and water for only 15 seconds, is insufficient for thorough surgical hand-washing.

Correct Answer: D

Rationale: The absence of breath sounds on the affected side is a critical finding that may indicate a tension pneumothorax, a life-threatening condition requiring immediate intervention. This situation can lead to a shift of the mediastinum and impaired ventilation. Bubbling in the water seal chamber is an expected finding in a chest tube drainage system and indicates proper functioning. Drainage greater than 70 ml/hour is a concern but does not require immediate reporting unless it continues at a high rate or is associated with other symptoms. Tidaling in the water seal chamber is a normal fluctuation and indicates the chest tube system is patent and functioning correctly.

Correct Answer: A

Rationale: When auscultating the chest, normal breathing sounds are expected in a healthy individual. Wheezing is a high-pitched whistling sound that indicates narrowed airways and is often heard in conditions like asthma. Crackles are fine, crackling sounds heard on inspiration or expiration and are associated with conditions like pneumonia or heart failure. Stridor is a high-pitched, harsh sound heard during inspiration due to upper airway obstruction. Therefore, choices B, C, and D indicate abnormal respiratory findings, while choice A signifies normal breathing sounds.

Correct Answer: A

Rationale: The correct term the nurse will use to report scaling of the scalp is 'Dandruff.' Dandruff is characterized by scaling of the scalp that is often accompanied by itching. Choice B, 'Alopecia,' refers to hair loss, not scaling. Choice C, 'Pediculosis,' is the infestation of lice, not scaling. Choice D, 'Xerostomia,' pertains to dry mouth, which is unrelated to the described symptom of scaling of the scalp.
