An overweight client taking warfarin (Coumadin) has dry skin due to decreased arterial blood flow. What should the nurse instruct the client to do? Select all that apply.

Correct Answer: A

Rationale: To address dry skin and prevent chronic ulcers and infections in an overweight client on warfarin with decreased arterial blood flow, the nurse should instruct the client to apply lanolin or petroleum jelly to intact skin. This helps maintain skin integrity and moisture. Following a reduced-calorie, reduced-fat diet (Choice B) may be beneficial for weight management but is not directly related to skin care. Inspecting involved areas daily for new ulcerations (Choice C) is important for skin assessment and early intervention but does not specifically address dry skin. Instructing the client to limit activities of daily living (ADLs) (Choice D) is not necessary for addressing dry skin; in fact, promoting mobility and circulation through appropriate activities is crucial.

Correct Answer: D

Rationale: Tachycardia is a sign of diabetic ketoacidosis (DKA) in a patient with type 1 diabetes. In DKA, the body responds to hyperglycemia and dehydration by increasing heart rate. Polyuria (increased urination) is a symptom of diabetes but not specific to DKA. Bradycardia (slow heart rate) and dry skin are not typical signs of DKA; instead, tachycardia and other signs of volume depletion are more common.

Correct Answer: C

Rationale: Choice C is the correct answer. Clients with chronic renal failure should not skip dialysis sessions, as this can lead to serious complications. Dialysis is crucial for managing fluid and electrolyte balance in these clients. Choice A is incorrect because clients with renal failure often have fluid restrictions. Choice B is incorrect as high-sodium foods can worsen fluid retention in clients with renal failure. Choice D is incorrect because dietary restrictions are important in managing chronic renal failure, and eating whatever one wants can lead to further complications.

Correct Answer: A

Rationale: The correct answer is to eat within 10 to 15 minutes after the injection. Insulin lispro, also known as Humalog, is a rapid-acting insulin that starts working very quickly. Eating shortly after the injection helps match the food intake with the insulin action, reducing the risk of hypoglycemia. Choice B is incorrect because waiting 1 hour after the injection may lead to a mismatch between insulin activity and food intake. Choice C is incorrect as timing meals with lispro injections is essential to optimize glycemic control. Choice D is incorrect as eating 2 hours before the injection is not in alignment with the rapid action of insulin lispro and may lead to fluctuations in blood sugar levels.

Correct Answer: A

Rationale: A Stage 2 pressure ulcer typically presents as a shallow open ulcer with a red-pink wound bed. This appearance is characteristic of a Stage 2 pressure ulcer where there is partial thickness skin loss involving the epidermis and possibly the dermis. Choice B, a deep pocket of infection and necrotic tissues, is more indicative of a Stage 3 or Stage 4 pressure ulcer where the ulcer extends into deeper tissue layers. Choice C, an area of erythema that is painful to touch, is more commonly seen in early-stage pressure ulcers such as Stage 1. Choice D, visible subcutaneous tissue with sloughing, is characteristic of a more severe stage of pressure ulcer beyond Stage 2.

Correct Answer: B

Rationale: The platelet count is the most appropriate laboratory result to review in a client presenting with petechiae and ecchymosis. Petechiae and ecchymosis are indicative of potential bleeding issues, which can be caused by low platelet count or impaired platelet function. Platelets are essential for clotting, and a low platelet count can lead to bleeding disorders. Reviewing the platelet count will provide valuable information about the client's clotting ability. Choice A, red blood cell count, is not typically associated with petechiae and ecchymosis. Hemoglobin levels (Choice C) are more related to anemia than bleeding disorders like thrombocytopenia. White blood cell count (Choice D) is not directly linked to the presence of petechiae and ecchymosis, which are more specific to platelet-related issues.

Correct Answer: D

Rationale: Tachycardia is the correct symptom to expect in a patient with hyperkalemia. Hyperkalemia, or high potassium levels in the blood, can affect the electrical activity of the heart. Increased potassium levels can lead to changes in the heart's rhythm, potentially causing tachycardia (rapid heart rate) or other cardiac arrhythmias. Muscle cramps (choice A) are not typically associated with hyperkalemia. Hypertension (choice B) is not a common symptom of hyperkalemia; in fact, high potassium levels can sometimes cause low blood pressure. Bradycardia (choice C), or a slow heart rate, is usually not a primary symptom of hyperkalemia; instead, hyperkalemia tends to be associated with faster heart rates or arrhythmias.

Correct Answer: C

Rationale: Vision problems are a characteristic symptom of multiple sclerosis (MS) due to demyelination of the optic nerve. This can lead to issues such as optic neuritis, blurred vision, double vision, or even total vision loss. Muscle atrophy (Choice A) is not a primary symptom of MS but can occur as a secondary effect of decreased mobility. Severe pain (Choice B) is not a typical symptom of MS, though some individuals may experience pain related to muscle spasms or other factors. Hearing loss (Choice D) is not commonly associated with MS unless there is an unrelated concurrent condition affecting the auditory system.

Correct Answer: A

Rationale: The correct answer is weight loss. In hyperthyroidism, there is an excess production of thyroid hormones leading to an increased metabolic rate. This increased metabolism can result in weight loss despite normal or increased appetite. Choice B (Weight gain) is more commonly associated with hypothyroidism where the metabolic rate is decreased. Choice C (Tachycardia) is another common symptom of hyperthyroidism due to the effects of thyroid hormones on the heart, causing an increased heart rate. Choice D (Dry skin) is not a typical symptom of hyperthyroidism; instead, it is more commonly associated with hypothyroidism.
