Correct Answer: B

Rationale: During a gastric lavage procedure for upper gastrointestinal bleeding, inserting a large-bore NG tube is essential to effectively remove gastric contents and blood. This tube allows for efficient irrigation and suction, aiding in the removal of harmful substances from the stomach. Instilling a large volume of solution or using a cold irrigation solution can lead to complications such as fluid overload or hypothermia. Instructing the client to lie on their right side is not directly related to the gastric lavage procedure.

Correct Answer: C

Rationale: Educating the client on the importance of rising slowly when getting out of bed is crucial due to the risk of orthostatic hypotension associated with furosemide use. This precaution helps prevent dizziness and falls. Options A and D are incorrect as furosemide commonly causes hypokalemia and dehydration, respectively, rather than high potassium levels or overhydration. Option B is inaccurate as clients on furosemide need to reduce sodium intake to manage fluid retention.

Correct Answer: C

Rationale: Approaching a client with vision loss from the side can startle them and may lead to accidents or discomfort. It is important to approach them from the front so they are aware of your presence. Keeping objects in the same place aids in familiarity and reduces the risk of falls. High-wattage lighting enhances visibility for the client. Allowing extra time for tasks accommodates the client's potential slower pace and ensures they can perform tasks safely.

Correct Answer: B

Rationale: Dyspnea is a key finding indicating fluid overload in a client receiving packed RBCs. Fluid overload can lead to pulmonary edema, causing difficulty breathing or shortness of breath (dyspnea). Low back pain is not typically associated with fluid overload but can be more related to musculoskeletal issues. Hypotension and thready pulse are more indicative of hypovolemia (low fluid volume), not fluid overload.

Correct Answer: A

Rationale: To calculate the expected delivery date using Nagele's rule, begin by subtracting 3 months from the first day of the last menstrual period (April 12th), which results in January 12th. Then, add 7 days. Therefore, the expected delivery date would be January 19th (0119). This calculation method helps healthcare professionals estimate the client's due date.
