Correct Answer: C

Rationale: The correct answer is C: Identifying the offending agent, if possible. This is prioritized in contact dermatitis to prevent further exposure and recurrence. By identifying the specific irritant or allergen, the nurse can guide the patient in avoiding it, leading to effective management. Choices A, B, and D are incorrect because while promoting adequate perfusion, safe use of topical antihistamines, and teaching the use of an EpiPen may be relevant in certain situations, they do not directly address the root cause of contact dermatitis, which is exposure to the offending agent.

Correct Answer: B

Rationale: The correct answer is B: Nausea and vomiting. Chemotherapy commonly causes gastrointestinal side effects, such as nausea and vomiting, due to its impact on rapidly dividing cells in the digestive tract. This adverse effect can significantly impact a patient's quality of life and adherence to treatment. Pruritis (A), itching, is less common and usually not a primary side effect of chemotherapy. Altered glucose metabolism (C) is a potential effect of some chemotherapeutic agents but is not the most common adverse effect. Confusion (D) is not typically associated with chemotherapy and is more commonly seen with other medications or medical conditions.

Correct Answer: B

Rationale: The correct answer is B: Retinopathy. Tadalafil (Cialis) is contraindicated in patients with retinopathy due to the potential risk of worsening vision problems. Retinopathy is a serious eye condition commonly associated with diabetes, and using tadalafil can lead to further complications in the eyes. It is crucial for patients with retinopathy to avoid medications that can exacerbate their eye condition. Incorrect choices: A: Cataracts - Cataracts do not contraindicate the use of tadalafil. Tadalafil does not have a direct negative impact on cataracts. C: Hypotension - Hypotension is not a contraindication for tadalafil use. In fact, tadalafil can cause a drop in blood pressure, so it should be used with caution in patients with hypotension. D: Diabetic nephropathy - Diabetic nephropathy is not a direct contraindication for tadalafil use. Tadalafil is generally

Correct Answer: C

Rationale: The correct answer is C (900 mL) because the weight of 900 g corresponds to a blood loss of the same amount in milliliters. Blood density is close to that of water, so 1 g ? 1 mL. Therefore, a blood-soaked peripad weighing 900 g indicates a blood loss of 900 mL. Choice A (1800 mL) is incorrect as it doubles the weight instead of converting it to milliliters. Choice B (450 mL) is incorrect as it halves the weight. Choice D (90 mL) is incorrect as it divides the weight by 10, which is too small for the blood loss indicated.

Correct Answer: D

Rationale: The correct answer is D because the patient's symptoms of pounding headache, visual changes, and epigastric pain are classic signs of worsening preeclampsia, indicating a significant increase in blood pressure and potential progression to eclampsia (seizures). Immediate medical intervention is crucial to prevent complications. A: Gastrointestinal upset does not explain the combination of symptoms presented. B: Magnesium sulfate is used to prevent seizures in preeclampsia but does not cause these specific symptoms. C: Anxiety does not typically present with the specific physical symptoms mentioned.
