Correct Answer: A

Rationale: To calculate the mL to be administered, convert 250 mg to grams (0.25 g). Then, set up a proportion: (0.25 g / 3 g) x 5 mL = 0.4167 mL, which rounds to 0.4 mL. Therefore, the healthcare professional would administer 0.4 mL per dose. Choice B (0.3 mL) is incorrect because it does not reflect the accurate calculation. Choice C (0.5 mL) is incorrect as it does not consider the correct conversion and calculation. Choice D (0.6 mL) is incorrect as it provides a value higher than the accurate calculation.

Correct Answer: B

Rationale: The correct answer is B: Peripheral edema. In heart failure, the heart's inability to pump effectively can lead to fluid backup, causing swelling in the extremities, known as peripheral edema. Monitoring for peripheral edema is crucial as it is a common sign of worsening heart failure. Choices A, C, and D are incorrect because increased energy, elevated heart rate, and improved lung sounds are not typical findings in heart failure. Increased energy is not usually associated with heart failure, an elevated heart rate may occur as a compensatory mechanism but is not a direct sign of heart failure, and improved lung sounds are not expected in heart failure which often presents with crackles or wheezes due to pulmonary congestion.

Correct Answer: A

Rationale: Corrected Rationale: The client with a cystocele should perform Kegel exercises to strengthen the pelvic floor muscles, reducing the risk of pelvic organ prolapse and stress urinary incontinence. Kegel exercises specifically target the muscles that support the pelvic organs. Isometric exercises focus on static muscle contractions and may not be as effective as Kegel exercises for strengthening the pelvic floor. Circumduction exercises involve circular movements at joints and are not specific to pelvic floor muscle strengthening. Uterine extension exercises do not directly target the pelvic floor muscles and are not indicated for cystocele management.

Correct Answer: C

Rationale: The correct adverse effect of prednisone that the nurse should emphasize is hyperglycemia. Prednisone is known to increase blood sugar levels, leading to hyperglycemia. While weight gain and other metabolic changes are possible side effects, hyperglycemia is a more critical concern due to the risk of uncontrolled blood sugar levels and its impact on overall health. Insomnia and hypertension are not typically associated with prednisone use, making them less relevant to emphasize during client education.

Correct Answer: A

Rationale: Corrected Rationale: Metformin should be taken with food to minimize gastrointestinal side effects. Choice A is the correct answer as taking metformin with meals can help reduce the likelihood of experiencing gastrointestinal side effects like diarrhea and nausea, which are common side effects of metformin. Choice B is incorrect because metformin actually helps lower blood sugar levels and does not cause hyperglycemia. Choice C is incorrect as metformin is usually taken twice or even three times a day, not just once daily. Choice D is incorrect because metformin is an oral medication, not an injectable one.
