Correct Answer: B

Rationale: The correct answer is B: Quadriceps setting. After surgery, quadriceps setting exercises are crucial for preventing muscle atrophy and maintaining joint mobility. Bladder control (A) is important but typically not the major early problem. Client education (C) and use of aids for ambulation (D) are important aspects of care but not the primary concern immediately post-surgery. Quadriceps setting helps prevent complications and promote early mobility.

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: The correct answer is C (30 seconds) because the maximum recommended time for suctioning a patient is typically around 10-15 seconds for each pass. Prolonged suctioning can lead to tissue damage, hypoxia, and increased risk of infection. In this case, given the patient's symptoms and medical history (vomiting, weight loss, dehydration, hypotension), it is crucial to limit suction time to prevent further complications. Choices A, B, and D are incorrect as they exceed the safe duration for suctioning and increase the risk of harm to the patient. Choice D, in particular, is significantly longer than the recommended time and could pose serious risks to the patient's health in this situation.

Correct Answer: C

Rationale: Rationale: C: Monitoring body temperature is essential for early detection of infection or fever, which can indicate disease exacerbation in SLE clients. A: Exposure to sunlight can worsen SLE symptoms due to photosensitivity. B: Activity limitations are crucial to prevent flare-ups and reduce disease progression in SLE. D: Corticosteroids should not be stopped abruptly without healthcare provider guidance to prevent symptom recurrence and adrenal insufficiency.

Correct Answer: C

Rationale: The correct answer is C. Aling Maria is admitted for myxedema, which is severe hypothyroidism. Symptoms of hypothyroidism include lethargy, weight gain, slow speech, and decreased respiratory rate. Bradycardia, weight loss, heart failure, and diarrhea are not typical symptoms of myxedema. Tachycardia, constipation, and exopthalmus are more commonly associated with hyperthyroidism. Hypothermia, weight loss, and increased respiratory rate are not consistent with myxedema. Thus, choice C is the most appropriate initial assessment for Aling Maria.
