A client asks the nurse to look at a mole located on the back. The client tells the nurse that the mole has changed from brown to black and enlarged in size. Which is the priority nursing action?
Advise the client to see his healthcare provider for immediate evaluation.
Encourage the client to keep checking the mole with a magnifying mirror.
Ask the client if he often spends time outside in the sun without a shirt.
Offer to teach a family member how to monitor the skin around the mole.
The Correct Answer is A
Rationale:
A. Changes in a mole's color, size, or shape could indicate melanoma, a serious type of skin cancer. Immediate evaluation by a healthcare provider is critical for early diagnosis and treatment.
B. While monitoring the mole is important, immediate professional evaluation is the priority to rule out malignancy.
C. Assessing sun exposure is relevant for skin cancer risk, but it is not the immediate priority in this scenario.
D. Teaching a family member to monitor the mole is not sufficient when there is a significant change that requires professional evaluation.

Correct Answer is B
Explanation
Rationale:
A. Insulin requirements generally increase as pregnancy progresses due to the growing placenta and hormones that cause insulin resistance, not fluctuate significantly.
B. Insulin requirements typically begin to increase around 18 weeks of gestation and continue to rise until approximately 36 weeks due to increased insulin resistance caused by placental hormones.
C. While insulin needs do increase, they do not typically double or quadruple during the second trimester. The increase is more gradual.
D. Insulin requirements increase during pregnancy and may decrease after delivery as the placenta is no longer present, removing the source of insulin resistance.
Correct Answer is C
Explanation
Rationale:
A. The combination of glucose and insulin is used to shift potassium into cells, which would lower serum potassium levels further; this is not appropriate for treating hypokalemia.
B. Increasing dietary intake of potassium is important but not sufficient to correct a serum potassium level as low as 2.5 mEq/L, which requires more immediate intervention.
C. A potassium level of 2.5 mEq/L is critically low and can lead to life-threatening cardiac arrhythmias. The healthcare provider should be informed immediately to initiate potassium replacement therapy, likely via intravenous infusion.
D. Hourly urinary output measurements may be useful but are not the immediate priority in treating severe hypokalemia.
