The nurse receives a health care provider's prescription to change a patient's IV from D5. half-normal saline with 40 mEq KCl/L to DSNS with 20 mEq KCl/L. Which set of serum laboratory values supports the rationale for this IV prescription change?
Sodium level of 136 mEq/L, potassium level of 4.5 mEq/L.
Sodium level of 145 mEq/L, potassium level of 4.8 mEq/L.
Sodium level of 135 mEq/L, potassium level of 3.6 mEq/L.
Sodium level of 144 mEq/L, potassium level of 3.7 mEq/L.
The Correct Answer is C
Choice A rationale:
The sodium level is within the normal range, but the potassium level is slightly elevated. This does not support the rationale for changing the IV prescription to a lower potassium concentration.
Choice B rationale:
The sodium level is slightly elevated, and the potassium level is within the normal range. This does not support the rationale for changing the IV prescription to a lower potassium concentration.
Choice C rationale:
Sodium level of 135 mEq/L, potassium level of 3.6 mEq/L is the correct answer. In this option, both sodium and potassium levels are within normal ranges. Changing the IV prescription to DSNS with 20 mEq KCl/L ensures that the patient receives adequate hydration (from the dextrose and normal saline) without causing hyperkalemia.
Choice D rationale:
The sodium level is slightly elevated, and the potassium level is within the normal range. This does not support the rationale for changing the IV prescription to a lower potassium concentration.

Correct Answer is A
Explanation
Choice B rationale:
A decrease in plasma renin levels is not a known cause of primary hypertension. Primary hypertension often has no identifiable cause, and it is a diagnosis of exclusion.
Choice C rationale:
Too much plaque in the blood vessels describes atherosclerosis, which is a risk factor for hypertension but not the direct cause of primary hypertension. Plaque buildup narrows arteries and increases resistance, contributing to elevated blood pressure.
Choice D rationale:
Kidney disease can cause secondary hypertension but is not the most common cause of primary hypertension. Primary hypertension, also known as essential hypertension, is the most common form, and its exact cause remains unknown in many cases.
Correct Answer is B
Explanation
Choice A rationale:
Flossing using thick tape floss can cause trauma to the gums and may lead to bleeding in patients with thrombocytopenia. Patients with low platelet counts are at risk of excessive bleeding from minor injuries, and using thick tape floss could potentially harm the gums and exacerbate bleeding.
Choice B rationale:
Shaving using an electric razor is a safe option for patients with thrombocytopenia. Electric razors do not pose a significant risk of cuts or nicks, reducing the likelihood of bleeding, which is crucial for patients with low platelet counts.
Choice C rationale:
Wearing flip-flops to go walking may not be the safest option for a patient with thrombocytopenia. If the patient accidentally stubs their toe or injures their foot while wearing flip-flops, it could lead to bleeding. Closed-toe, comfortable shoes provide better protection against foot injuries.
Choice D rationale:
Brushing using a stiff-bristle toothbrush can be harmful to the gums, especially for patients with thrombocytopenia. Stiff-bristle toothbrushes can cause gum irritation and bleeding. Patients with low platelet counts should use a soft-bristle toothbrush to minimize the risk of gum injury.
