Nokea
A nurse is caring for a client who has a prescription for lactated Ringers by continuous IV infusion to replace output from an NG tube. Which of the following findings should indicate to the nurse that this therapy is effective?
- A. Urine specific gravity 1.035
- B. Urine specific gravity 1.020
- C. Decreased skin turgor
- D. Dry mucous membranes
Correct Answer: B
Rationale: The correct answer is B: Urine specific gravity 1.020. This finding indicates that the kidneys are effectively concentrating urine, which means fluid balance is being maintained. A specific gravity of 1.020 is within the normal range, suggesting adequate hydration. A high specific gravity like 1.035 (choice A) indicates dehydration. Decreased skin turgor (choice C) and dry mucous membranes (choice D) are signs of dehydration, not effectiveness of therapy.

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 caring for a client who has chronic venous insufficiency. Which of the following areas should the nurse assess for the presence of a venous ulcer?
- A. Tip of the toes
- B. Medial malleolus (ankle)
- C. Ball of the foot
- D. Heel of the foot
Correct Answer: B
Rationale: The correct answer is B: Medial malleolus (ankle). Venous ulcers commonly occur in areas where there is poor circulation, such as the lower legs. The medial malleolus is a common site for venous ulcers in individuals with chronic venous insufficiency due to pooling of blood in the lower extremities. Assessing this area is crucial for early detection and appropriate management. Choices A, C, and D are incorrect as venous ulcers typically develop in areas with high venous pressure and poor circulation, such as the lower legs, not at the tip of the toes, ball of the foot, or heel.
A nurse is caring for a client who is receiving vancomycin intermittent IV bolus therapy for methicillin-resistant Staphylococcus aureus (MRSA). Which of the following findings is an indication to the nurse that the client is experiencing an adverse effect of the medication?
- A. The client reports ringing in the ears.
- B. The client is becoming flushed.
- C. The client reports increased thirst.
- D. The client has a decreased urine output.
Correct Answer: B
Rationale: The correct answer is B: The client is becoming flushed. Flushing is a common adverse effect of vancomycin, indicating a possible allergic reaction or infusion reaction. Flushing can be a sign of red man syndrome, a severe reaction to vancomycin. The nurse should monitor closely and report this finding to the healthcare provider.
Incorrect Answer Rationale:
A: The client reports ringing in the ears - this is a potential adverse effect of vancomycin, but not as critical as flushing.
C: The client reports increased thirst - this is not typically associated with vancomycin adverse effects.
D: The client has a decreased urine output - this may indicate nephrotoxicity, a known side effect of vancomycin, but flushing is more indicative of an immediate adverse reaction.
A nurse is teaching a client about preventing the transmission of HIV. Which of the following information should the nurse include?
- A. Only symptomatic individuals can transmit HIV.
- B. Medication is available that will reduce the risk for HIV transmission.
- C. Sharing utensils can spread HIV.
- D. Frequent handwashing prevents HIV transmission.
Correct Answer: B
Rationale: The correct answer is B: Medication is available that will reduce the risk for HIV transmission. This is correct because antiretroviral therapy can significantly reduce the viral load in individuals living with HIV, making them less likely to transmit the virus to others. Option A is incorrect as asymptomatic individuals can also transmit HIV. Option C is incorrect as HIV is not spread through casual contact like sharing utensils. Option D is incorrect as handwashing is important for general hygiene but does not specifically prevent HIV transmission.
A nurse is caring for a client who has deep-vein thrombosis and is receiving heparin via continuous IV infusion. The clients weight is 80 kg (176.4 lb). Using the client information provided, which of the following actions should the nurse take?
- A. Increase the infusion rate.
- B. Administer protamine sulfate immediately.
- C. Stop the heparin infusion for 1 hr.
- D. Decrease the heparin dose.
Correct Answer: C
Rationale: The correct answer is C: Stop the heparin infusion for 1 hr. This is because the client's weight is crucial in determining the appropriate heparin dosage. Heparin is usually dosed based on the client's weight to prevent complications such as bleeding or clotting. In this case, the client's weight of 80 kg indicates a specific dose range for heparin. Stopping the infusion for 1 hour allows the nurse to reassess the client's condition and potentially adjust the heparin dosage to ensure it is safe and effective.
A: Increasing the infusion rate without proper assessment can lead to overdose and increased risk of bleeding.
B: Administering protamine sulfate is the antidote for heparin overdose, not indicated in this scenario.
D: Decreasing the heparin dose without assessment may result in inadequate anticoagulation and increased risk of clot formation.
