Correct Answer: D

Rationale: The correct answer is D because an MRI is a noninvasive imaging test that uses magnetic energy to produce detailed images of internal body parts. This explanation is accurate and informative, reassuring the patient. A is incorrect because it describes electromyography (EMG), not MRI. B is incorrect as it describes electroencephalography (EEG), not MRI. C is incorrect because it describes a nuclear medicine test, not MRI. In summary, only option D provides a correct and relevant description of what to expect during an MRI.

Correct Answer: B

Rationale: The correct answer is B because it encourages the patient to reflect on their own thoughts and identify potential causes of their fatigue. It allows the patient to express their own insights and helps the nurse understand the underlying reasons for the fatigue. Choice A focuses on stress, which may not be the main cause of fatigue. Choice C is irrelevant to exploring the fatigue further. Choice D assumes that lack of sleep is the main issue, which may not be the case for the patient.

Correct Answer: C

Rationale: The correct formula to calculate the appropriate morphine dose for the client is 5 mg/kg of body weight. This is the most suitable formula because morphine dosing is typically based on weight to ensure appropriate pain management and to prevent adverse effects. By using this formula, the nurse can calculate the exact dose based on the client's weight, providing personalized care. Choice A (1 mg/kg of body weight) is too low of a dose and may not effectively manage severe pain. Choice B (5 mg/70kg of body weight) is not ideal as it does not account for variations in weight among individuals. Choice D (10mg/70kg of body weight) would result in an overdose for most patients, potentially causing serious harm. Therefore, by using the formula of 5 mg/kg of body weight, the nurse can ensure that the morphine dose is appropriate and safe for the client.

Correct Answer: C

Rationale: Step 1: Most clients are not hospitalized long after a mastectomy - Correct. This is because mastectomy is often performed as an outpatient procedure, and clients are discharged home shortly after surgery. Step 2: The adverse effects of mastectomy are not immediate - Incorrect. Adverse effects may occur post-surgery, but early discharge is not solely due to immediate adverse effects. Step 3: The wound of the surgery is not highly contagious - Incorrect. Mastectomy wounds are not contagious, and isolation precautions are not necessary. Step 4: Suicidal tendencies in women undergoing mastectomy are not high - Incorrect. While emotional support is crucial, early discharge is not primarily due to suicidal tendencies. Summary: Choice C is correct because mastectomy clients are typically not hospitalized long, making early discharge instructions and home care arrangements necessary. Choices A, B, and D are incorrect as they do not directly relate to the primary reason for early discharge and home care planning.

Correct Answer: C

Rationale: The correct answer is C: 12 to 18 g/100mL. Normal hemoglobin values typically range from 12 to 18 g/100mL in adults. This range reflects the normal concentration of hemoglobin in the blood and is commonly used as a reference range in clinical practice. Choices A, B, and D are incorrect because they do not fall within the typical normal range for hemoglobin levels. Choice A (38% to 48%) is a percentage range, not a direct measurement of hemoglobin concentration. Choice B (48 to 54 mg%) and Choice D (27 to 36 g/dL) are outside the normal range for hemoglobin levels in adults. Therefore, the most appropriate and accurate choice among the options provided is C (12 to 18 g/100mL) based on standard reference values for hemoglobin concentration in the blood.
