A client with a history of heart failure presents with increased shortness of breath and swelling in the legs. What is the most important assessment for the LPN/LVN to perform?

Correct Answer: C

Rationale: Checking for jugular vein distention is crucial in assessing fluid overload in clients with heart failure. Jugular vein distention indicates increased central venous pressure, which can be a sign of worsening heart failure. Monitoring oxygen saturation (Choice A) is important but may not provide immediate information on fluid status. Assessing the apical pulse (Choice B) is relevant for monitoring heart rate but may not directly indicate fluid overload. Measuring urine output (Choice D) is essential for assessing renal function and fluid balance but does not provide immediate information on fluid overload in this scenario.

Correct Answer: C

Rationale: Ensuring the water seal chamber is filled to the appropriate level is crucial to maintain the effectiveness of the chest tube drainage system. This step helps prevent air from entering the pleural space, ensuring proper lung re-expansion. 'Milking' the chest tube is not recommended as it can cause damage to the chest tube and surrounding tissues. Clamping the chest tube is not advisable as it can lead to tension pneumothorax. Securing the chest tube to the bed is important for stability but does not directly impact the functioning of the chest tube.

Correct Answer: A

Rationale: The correct answer is to administer nitroglycerin sublingually. Administering nitroglycerin sublingually is the priority action for a client with chest pain and a history of coronary artery disease. Nitroglycerin helps dilate the coronary arteries, improving blood flow to the heart muscle and providing rapid relief of chest pain. Obtaining a 12-lead ECG, measuring vital signs, and administering oxygen are important actions but should follow the administration of nitroglycerin in the management of chest pain in a client with coronary artery disease.

Correct Answer: B

Rationale: The correct answer is B: Liver function tests. While a client is taking metformin, monitoring liver function tests is crucial to assess for potential hepatic side effects. Metformin is primarily eliminated by the liver, and monitoring liver function tests helps in early detection of any liver-related complications. Choices A, C, and D are incorrect. A complete blood count (CBC) is not specifically required for monitoring metformin therapy. Serum electrolytes are not directly impacted by metformin, making it less relevant for monitoring this medication. Renal function tests are important for some other diabetes medications, but in the case of metformin, liver function tests take precedence due to its hepatic metabolism.

Correct Answer: B

Rationale: Measuring the client's oxygen saturation level is the most important assessment in this scenario. Oxygen saturation level reflects how well the client is oxygenating, which is crucial in assessing the effectiveness of oxygen therapy for a client with COPD. Monitoring the respiratory rate and effort (Choice A) is important but assessing oxygenation with saturation levels takes precedence. While arterial blood gas levels (Choice C) provide comprehensive information, checking oxygen saturation is a quicker and more immediate way to assess oxygenation status. Checking blood pressure (Choice D) is not the priority when evaluating the effectiveness of oxygen therapy in COPD.
