A client with a history of congestive heart failure (CHF) is admitted with dyspnea and a productive cough. What is the most important assessment for the LPN/LVN to perform?

Correct Answer: B

Rationale: Auscultating lung sounds is crucial for assessing the extent of congestion in a client with CHF. The presence of crackles or wheezing can indicate fluid accumulation in the lungs, a common complication of CHF. Monitoring urine output (Choice A) is important to assess renal function but is not the priority in this situation. While assessing the apical pulse (Choice C) and checking blood pressure (Choice D) are important in managing CHF, they do not provide immediate information about the respiratory status and congestion level in the lungs, making auscultating lung sounds the most critical assessment.

Correct Answer: A

Rationale: To calculate the mL to administer, use the formula: Dose required (mg) · Stock concentration (mg/mL) = Volume to administer (mL). In this case, 10 mg · 40 mg/mL = 0.25 mL. However, when rounding to the nearest tenth, the answer should be 0.3 mL. Therefore, the nurse should administer 0.3 mL. Choice A is the correct answer. Choice B (0.25 mL) is the result obtained before rounding. Choice C (0.4 mL) and Choice D (0.5 mL) are incorrect calculations.

Correct Answer: A

Rationale: The correct action the nurse should take first is to auscultate bowel sounds. This step is crucial to assess bowel activity before proceeding with palpation or administering medications. Assessing bowel sounds can provide valuable information about bowel motility and potential obstructions. Administering an antiemetic or offering pain medication may be necessary but should come after assessing bowel sounds to ensure appropriate treatment. Palpating the abdomen should be avoided initially to prevent potential discomfort or complications, especially if there is suspected abdominal pathology.

Correct Answer: D

Rationale: In acute pancreatitis, hypocalcemia (low serum calcium) is a critical finding that is associated with a poor prognosis and requires immediate attention. Serum amylase and lipase are typically elevated in acute pancreatitis due to pancreatic inflammation, but they are not indicators of severity. Blood glucose levels may be elevated due to stress or underlying conditions but are not directly related to the severity of acute pancreatitis. Therefore, the most concerning value in this scenario is the low serum calcium level, which can have significant implications for the client's prognosis.

Correct Answer: B

Rationale: When caring for a client with dementia, it is crucial to understand that confusion often arises after relocating to new surroundings. This change can disrupt familiar routines and trigger increased disorientation and confusion. Choice A is correct because confusion in the elderly is not a normal part of aging. Choice C is incorrect because confusion in dementia is primarily due to changes in the brain associated with the disease, not just irreversible brain pathology. Choice D is incorrect because while adequate sleep is important for overall health, it alone cannot prevent or cure confusion associated with dementia.

Correct Answer: B

Rationale: The correct way to transcribe the dosage of three tenths of a milligram of levothyroxine IV STAT is 0.3 mg. When expressing decimals less than 1, there should be a leading zero before the decimal point. Choice A is incorrect (.3 mg) because it lacks the leading zero. Choice C (0.30 mg) is incorrect as it includes a trailing zero after the decimal point, which is unnecessary. Choice D (3/10 mg) is incorrect as it presents the dosage as a fraction, which is not the standard format for transcribing medication dosages. Therefore, B (0.3 mg) is the most appropriate and accurate way to document this prescription on the client's medical record.

Correct Answer: A

Rationale: A decrease in heart rate can indicate improved fluid balance and successful treatment of fluid volume deficit. When a client is experiencing fluid volume deficit, the heart rate typically increases as a compensatory mechanism to maintain cardiac output. As fluid volume is restored and the deficit is corrected, the heart rate should decrease back towards a normal range. Choices B, C, and D are less likely to be directly related to the successful treatment of fluid volume deficit. An increase in blood pressure may occur as a compensatory response to fluid volume deficit; a decrease in respiratory rate is not a typical indicator of fluid volume deficit correction; and an increase in urine output can be a sign of improved kidney function but may not directly reflect fluid volume status.

Correct Answer: A

Rationale: Choice A is correct because performing ankle and knee exercises every hour helps prevent contractures and other adverse effects of immobility. Contractures are a common complication of immobility, and range of motion (ROM) exercises can help maintain joint flexibility and prevent contractures. This statement indicates an understanding of the teaching provided by the healthcare provider. Choices B, C, and D are incorrect. Holding the breath when rising from a sitting position can increase the risk of orthostatic hypotension, not reduce adverse effects of immobility. Removing antiembolic stockings while in bed can compromise their effectiveness in preventing deep vein thrombosis (DVT), which is not a measure to reduce immobility-related complications. Having a partner help change positions every 4 hours may not be frequent enough to prevent immobility-related complications effectively; changing positions more frequently is usually recommended to prevent issues like pressure ulcers and muscle stiffness.

Correct Answer: A

Rationale: Performing a bladder scan is the initial step to assess for urinary retention in a postoperative client. This non-invasive technique helps determine the volume of urine in the bladder, guiding further interventions. Encouraging the client to drink fluids (Choice B) may be beneficial but is not the priority when assessing for urinary retention. Inserting a straight catheter (Choice C) should not be the initial action without first assessing for retention. Administering a diuretic (Choice D) should not be done without confirming the need through assessment.
