A nurse in an emergency department is assessing a client who is overusing prescribed diuretics and has a sodium level of 127 mEq/L. Which of the following laboratory findings should the nurse expect?
- A. Low urine specific gravity
- B. High urine specific gravity
- C. Elevated potassium levels
- D. Decreased potassium levels
Correct Answer: A
Rationale: The correct answer is A: Low urine specific gravity. Excessive diuretic use can lead to volume depletion and low sodium levels. Low sodium levels cause the kidneys to excrete more water, resulting in dilute urine with low specific gravity. High urine specific gravity would indicate concentrated urine, which is not expected in this situation. Elevated potassium levels (choice C) are not typically associated with overuse of diuretics, as diuretics can actually lead to potassium loss. Similarly, decreased potassium levels (choice D) are commonly seen with diuretic use due to increased excretion of potassium by the kidneys.

A nurse is inspecting the skin of a client who has basal cell carcinoma. The nurse should identify which of the following lesion characteristics on the clients skin?
- A. A pearly, waxy nodule
- B. A scaly, red patch
- C. A dark, irregular mole
- D. A firm, painless lump
Correct Answer: A
Rationale: The correct answer is A: A pearly, waxy nodule. Basal cell carcinoma typically presents as a pearly, waxy nodule on the skin. This characteristic appearance is due to the growth of abnormal cells in the basal cell layer of the skin. The nodule may also have small blood vessels visible on its surface. This presentation is distinct from other skin lesions. Choice B, a scaly red patch, is more indicative of conditions like psoriasis or eczema. Choice C, a dark irregular mole, is more suggestive of melanoma. Choice D, a firm, painless lump, is more characteristic of conditions like lipomas or fibromas. Thus, the correct answer is A based on the specific characteristics of basal cell carcinoma.
A nurse is providing teaching to a client who has a new prescription for warfarin. Which of the following medications should the nurse instruct the client to avoid? (Select all that apply)
- A. Ferrous sulfate
- B. Echinacea
- C. Aspirin
- D. Dextromethorphan
- E. Naproxen
Correct Answer: C, E
Rationale: The correct answer is C (Aspirin) and E (Naproxen). Aspirin and Naproxen are both NSAIDs that can increase the risk of bleeding when taken with warfarin, which is an anticoagulant. The combination can lead to excessive anticoagulation and potential bleeding complications. Ferrous sulfate (A) does not interact significantly with warfarin. Echinacea (B) is an herbal supplement that may have interactions with some medications, but not warfarin specifically. Dextromethorphan (D) is a cough suppressant and does not have a significant interaction with warfarin. In summary, Aspirin and Naproxen should be avoided with warfarin due to the increased risk of bleeding, while the other options do not have significant interactions with warfarin.
A nurse is planning care for a client who is scheduled for surgery and has a latex allergy. Which of the following actions should the nurse plan to take?
- A. Use only powder-free latex gloves.
- B. Place monitoring cords and tubes in a stockinette.
- C. Avoid using iodine-based antiseptics.
- D. Administer prophylactic antihistamines.
Correct Answer: B
Rationale: The correct answer is B: Place monitoring cords and tubes in a stockinette. This is important for the client with a latex allergy because stockinettes provide a barrier between the latex-containing materials and the client's skin, reducing the risk of allergic reactions. Using powder-free latex gloves (choice A) is a good practice, but it is not directly addressing the risk of exposure to latex for the client. Avoiding iodine-based antiseptics (choice C) is not necessary unless the client has a specific allergy to iodine. Administering prophylactic antihistamines (choice D) is not a standard practice for latex allergies and may not prevent an allergic reaction.
A nurse is assessing a clients understanding of a surgical procedure prior to witnessing their signature on the informed consent form. The nurse determines that the client does not understand what the procedure will involve. Which of the following actions should the nurse take?
- A. Proceed with obtaining the signature.
- B. Explain the procedure in detail.
- C. Contact the provider who will be performing the procedure.
- D. Have the client sign the form and address concerns later.
Correct Answer: C
Rationale: The correct answer is C: Contact the provider who will be performing the procedure. This is the best course of action because the provider is the most qualified individual to explain the procedure in detail and address any concerns the client may have. By involving the provider, the client can receive accurate and comprehensive information directly from the source. Proceeding with obtaining the signature (A) without ensuring the client's understanding can lead to potential legal and ethical issues. Explaining the procedure in detail (B) may not be sufficient if the client still has questions or concerns. Having the client sign the form and addressing concerns later (D) is not appropriate as it prioritizes paperwork over patient understanding and safety.
A nurse is providing teaching to a group of clients about the prevention of coronary artery disease. Which of the following information should the nurse include in the teaching?
- A. Walk 30 min daily at a comfortable pace.
- B. Avoid all sources of dietary fat.
- C. Increase sodium intake to prevent dehydration.
- D. Only exercise if experiencing symptoms.
Correct Answer: A
Rationale: Correct Answer: A: Walk 30 min daily at a comfortable pace.
Rationale: Regular physical activity, such as walking, helps prevent coronary artery disease by improving cardiovascular health, maintaining a healthy weight, and reducing stress. Walking for 30 minutes daily at a comfortable pace can improve circulation, lower blood pressure, and reduce the risk of developing heart disease.
Summary of other choices:
B: Avoiding all sources of dietary fat is not recommended as the body needs healthy fats for various functions.
C: Increasing sodium intake does not prevent coronary artery disease and can actually contribute to hypertension, a risk factor for the disease.
D: Only exercising when experiencing symptoms is not proactive in preventing coronary artery disease and may lead to missed opportunities for prevention.
