A nurse is teaching a client who has a new prescription for metformin extended-release tablets.
Which of the following statements by the client indicates an understanding of the teaching?
"I will take the medication in the morning.”
"I will expect to gain weight.”
"I will take the medication on an empty stomach.”
"I will avoid crushing this medication.”
The Correct Answer is D
Choice A rationale:
The statement, "I will take the medication in the morning," indicates lack of understanding. Metformin is usually taken with large meals, and taking it in the morning is not the best timing.
Choice B rationale:
The statement, "I will expect to gain weight," is incorrect. Weight gain is not an expected side effect of metformin. In fact, metformin is often associated with weight loss or weight maintenance, especially in individuals with diabetes, as it helps improve insulin sensitivity and glucose metabolism.
Choice C rationale:
The statement, "I will take the medication on an empty stomach," is incorrect for extended-release metformin tablets. Unlike immediate-release metformin, extended-release tablets should be taken with meals to reduce the risk of gastrointestinal side effects.
Choice D rationale:
The statement, "I will avoid crushing this medication," is correct. Metformin extended-release tablets should never be crushed or broken, as it can affect the way the medication is released into the body. Crushing or breaking the tablet can lead to a sudden release of a large amount of metformin, potentially causing an overdose.

Correct Answer is C
Explanation
Choice A rationale:
Measuring the amount of time the child can hear the sound is not the correct action when performing Weber's test. Weber's test is used to assess hearing acuity and lateralization. In this test, a vibrating tuning fork is placed in the middle of the patient's forehead, and the patient is asked if the sound is heard equally in both ears or if it is louder in one ear. This helps identify whether there is a conductive or sensorineural hearing loss. The duration of hearing the sound is not relevant to this test.
Choice B rationale:
Obtaining a tympanogram reading is not necessary before initiating Weber's test. Tympanometry assesses the movement of the eardrum in response to changes in air pressure and can help diagnose conditions like middle ear effusion or eustachian tube dysfunction. However, Weber's test focuses on lateralization of sound and does not require tympanogram readings.
Choice C rationale:
Placing a vibrating tuning fork on the top of the child's head is the correct action for performing Weber's test. By doing so, the nurse can assess whether the sound is perceived equally in both ears or if it is lateralized to one ear. If the sound is lateralized, it can provide valuable information about the type of hearing loss the child may have, whether it's conductive or sensorineural.
Choice D rationale:
Holding a vibrating tuning fork 1 to 2 cm (0.4 to 0.8 in) from the child's ears is not the correct technique for Weber's test. Placing the tuning fork directly on the patient's forehead is essential for accurate assessment. Holding it close to the ears can lead to misinterpretation of the test results.
Correct Answer is A
Explanation
- A. Correct. A hemoglobin level of 14.9 g/dL indicates that the client has an adequate amount of oxygen-carrying capacity in the blood, which is the goal of blood transfusion therapy.
- B. Incorrect. A WBC count of 12,000/mm3 is slightly elevated and may indicate an infection or inflammation, which are not related to blood transfusion therapy.
- C. Incorrect. A potassium level of 48 mEq/L is dangerously high and may cause cardiac arrhythmias, muscle weakness, or paralysis. This is not an expected outcome of blood transfusion therapy and may indicate hemolysis or renal impairment.
- D. Incorrect. A BUN level of 18 mg/dL is within the normal range and does not reflect the effectiveness of blood transfusion therapy.
