Correct Answer: D

Rationale: To calculate the drops per minute for the client, first, convert the weight from pounds to kilograms by dividing 182 by 2.2, which equals 82.72 kg. Then, calculate the dose in mcg/min by multiplying the weight in kg by the rate (82.72 kg * 5 mcg/kg/min = 413.6 mcg/min). Next, convert 50 mg to mcg (50 mg * 1000 = 50,000 mcg). Divide the total mcg (50,000 mcg) by the dose per minute (413.6 mcg/min) to get approximately 121 gtt/min. However, since the drip factor is 60 gtt/ml, the correct answer is 124 gtt/min, ensuring the accurate administration rate of the medication. Therefore, choice 'D' is the correct answer. Choices 'A', 'B', and 'C' are incorrect as they do not accurately reflect the calculated drops per minute based on the given information.

Correct Answer: B

Rationale: In this scenario, the LPN should continue asking the mother questions about the child. The mother's behavior of looking at the floor may be a cultural practice, such as avoiding direct eye contact, which should be respected. By maintaining the conversation with the mother, the nurse acknowledges and respects her communication style, fostering trust and open dialogue. Option A is not the best choice as it may disregard the cultural context and the importance of the mother's input. Option C is unnecessary as the LPN can effectively handle the situation. Option D could be perceived as insensitive and may disrupt the rapport between the nurse and the mother.

Correct Answer: B

Rationale: When a 5-month-old infant vomits multiple times, there is a risk of developing metabolic alkalosis due to the loss of stomach acid. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. It is caused by the loss of hydrogen ions from the body, often through vomiting. Metabolic acidosis (choice A) is unlikely in this scenario because it is more commonly associated with conditions like renal failure or diabetic ketoacidosis. Choice C, increased serum hemoglobin levels, is not typically a direct consequence of vomiting. Choice D, decreased serum potassium levels, may occur with vomiting but is not the primary concern when a patient is vomiting excessively.

Correct Answer: D

Rationale: The correct answer is D because if the catheter is blocked or not draining, it may need irrigation to restore proper flow. Option A, 'Bladder scan shows 525 mL of urine,' does not necessarily indicate the need for irrigation as it could be within the expected range for catheter drainage. Option B, 'Urine has a strong odor,' may indicate a urinary tract infection but does not directly correlate with the need for catheter irrigation. Option C, 'The client reports abdominal discomfort,' could indicate various issues but does not specifically suggest the need for catheter irrigation.

Correct Answer: D

Rationale: The correct answer is to further assess the patient. 'ROM as needed' stands for Range of Motion, indicating that the patient should have their limbs moved to maintain joint flexibility and muscle strength. Before initiating any movements, it is crucial to assess the patient's current condition to determine their abilities and limitations. Restricting mobility (choice A) is not appropriate as it contradicts the purpose of ROM exercises. Realizing the patient is unable to move extremities (choice B) assumes without assessment and can lead to inappropriate care. Moving all the patient's extremities (choice C) without assessing the patient first can be harmful, as it may cause pain or injury if done incorrectly. Therefore, further assessment is necessary to provide safe and effective care.
