A nurse is caring for a client who has generalized petechiae and ecchymoses. The nurse should expect a prescription for which of the following laboratory tests?

Correct Answer: A

Rationale: The correct answer is A: Platelet count. Platelet count helps assess clotting abnormalities that could cause petechiae and ecchymoses. Petechiae and ecchymoses are often associated with bleeding disorders, so it is crucial to evaluate the platelet count to determine if there is a deficiency in platelets. Choices B, C, and D are incorrect because potassium level, creatinine clearance, and prealbumin do not directly relate to assessing clotting abnormalities associated with petechiae and ecchymoses.

Correct Answer: D

Rationale: The correct answer is D. Food exchange lists are valuable resources for individuals with diabetes as they provide structured meal planning guidance. This helps individuals manage their diabetes effectively by controlling their carbohydrate intake. Choices A, B, and C are incorrect because personal blogs may not provide reliable and evidence-based information, food label recommendations from the Institute of Medicine may not be specific for diabetes meal planning, and diabetes medication information from the Physicians' Desk Reference is not directly related to meal planning for diabetes management.

Correct Answer: C

Rationale: The correct action for the nurse when caring for a client with thrombocytopenia is to provide the client with a stool softener. Thrombocytopenia is characterized by a low platelet count, leading to increased bleeding tendencies. Providing a stool softener helps prevent constipation, reducing the likelihood of straining during bowel movements and subsequent bleeding. Encouraging the client to floss daily (choice A) is unrelated to managing thrombocytopenia. Removing fresh flowers from the client's room (choice B) pertains more to infection control than addressing thrombocytopenia. Avoiding serving raw vegetables (choice D) is not directly associated with managing thrombocytopenia symptoms.

Correct Answer: B

Rationale: Cheddar cheese is a rich source of calcium and should be recommended to clients with osteoporosis. While broccoli and almonds also contain calcium, cheddar cheese provides a higher amount per serving. Fortified orange juice may contain added calcium, but it is not as concentrated a source as cheddar cheese. Therefore, the best choice for a client with osteoporosis seeking a high calcium food is cheddar cheese.

Correct Answer: B

Rationale: The correct intervention for a client with acute diverticulitis is to initiate a low-fiber diet. A low-fiber diet helps manage acute diverticulitis by reducing irritation to the colon, allowing it to heal. Administering a cleansing enema (Choice A) can worsen diverticulitis by increasing pressure within the colon. Applying moist heat to the abdomen (Choice C) may provide comfort but does not address the underlying cause. Providing a clear liquid diet (Choice D) is not ideal for diverticulitis management as it lacks the necessary nutrients for healing and may not provide enough bulk to prevent further irritation.

Correct Answer: C

Rationale: The correct answer is C. A weight gain of 2.2 kg (5 lb) in 1 week can indicate fluid retention, a serious side effect of fluoxetine that should be reported to the provider. Choices A, B, and D are within normal ranges and are not alarming findings that would require immediate reporting to the provider. A heart rate of 80/min, blood pressure of 130/80 mm Hg, and a temperature of 37.2°C (99°F) are all within normal limits and not typically concerning in a client taking fluoxetine.

Correct Answer: C

Rationale: Enuresis is a common symptom of urinary tract infections in school-age children. It is often a presenting symptom due to irritation of the bladder. Periorbital edema (Choice A) is more indicative of conditions like nephrotic syndrome or renal disorders. Decreased frequency of urination (Choice B) is not typically associated with urinary tract infections. Diarrhea (Choice D) is not a common symptom of urinary tract infections but may occur due to other reasons like gastrointestinal infections.

Correct Answer: A

Rationale: The correct instruction for a client prescribed nitroglycerin sublingual tablets is to lie down before taking the medication. Nitroglycerin can cause a sudden drop in blood pressure leading to dizziness or fainting, so taking the medication while lying down helps prevent falls. Choice B is incorrect because nitroglycerin is usually taken on an empty stomach to enhance its absorption. Choice C is incorrect as taking a double dose of nitroglycerin can lead to low blood pressure and other adverse effects. Choice D is incorrect as nitroglycerin sublingual tablets should be stored in their original container at room temperature away from light and moisture, not in the refrigerator.

Correct Answer: D

Rationale: Administering the medication is appropriate for a stable lithium level of 0.8 mEq/L. A level of 0.8 mEq/L falls within the therapeutic range for lithium, indicating that the client is receiving an adequate dose to maintain therapeutic effects. Withholding the next dose, increasing the dosage, or discontinuing the medication would not be indicated at this lithium level as it is within the desired range for therapeutic benefit. Therefore, the correct action would be to continue administering the medication to ensure the client maintains the therapeutic level of lithium.
