The nurse plans to administer the adult client’s prescriptions which are metoprolol, hydrochlorothiazide, enoxaparin and atorvastatin.
The current laboratory values are; Serum potassium 5.2 mmol/L, Platelet Count 98,000/mm, Serum cholesterol 250 mg/dL and Serum Creatinine 1.2 mg/dL.
Which medication should the nurse hold and notify the prescriber?
Metoprolol.
Hydrochlorothiazide.
Enoxaparin.
Atorvastatin.
The Correct Answer is B
The nurse should hold and notify the prescriber because hydrochlorothiazide is a diuretic that can lower the serum potassium level. The client already has a high serum potassium level of 5.2 mmol/L, which is above the normal range of 3.5 to 5.0 mmol/L.
Giving hydrochlorothiazide could worsen the client’s condition and cause hypokalemia.
Choice A is wrong because metoprolol is a beta-blocker that can lower the blood pressure and heart rate.
The client’s blood pressure and heart rate are not given, so there is no reason to hold metoprolol based on the information provided.
Choice C is wrong because enoxaparin is an anticoagulant that can prevent blood clots. The client has a low platelet count of 98,000/mm, which is below the normal range of 150,000 to 450,000/mm.
However, this does not contraindicate the use of enoxaparin, unless the client has signs of bleeding or bruising.
Choice D is wrong because atorvastatin is a statin that can lower the serum cholesterol
level. The client has a high serum cholesterol level of 250 mg/dL, which is above the desirable level of less than 200 mg/dL.
Giving atorvastatin could help reduce the client’s risk of cardiovascular complications.

Correct Answer is D
Explanation
. Document the findings and continue to monitor the wound. This is because a 2-day-old wound that has a crust along the edges, is red and appears slightly swollen is likely in the inflammatory phase of wound healing. This phase is characterized by hemostasis, chemotaxis, and increased vascular permeability, which can
cause redness and swelling. The crust along the edges is formed by the clotting of blood and platelets.
These are normal signs of wound healing and do not indicate infection or complications.
Choice A is wrong because applying warm soaks to reduce inflammation can interfere with the natural process of wound healing and increase the risk of infection.
Choice B is wrong because notifying the health care provider immediately of the infection is not necessary unless there are other signs of infection such as fever, pus, foul odor, or increased pain.
Choice C is wrong because placing the client on contact (wound) precautions is not required for a 2-day-old wound that is not infected or draining. Wound precautions are only indicated for wounds that are colonized or infected by multidrug-resistant organisms.
Correct Answer is A
Explanation
This is the proper way to obtain a throat culture, which is a test to look for infections in the back of the throat.
Some possible explanations for the other choices are:
Choice B is wrong because there is no need to avoid eating or drinking after a throat culture.
The swab does not interfere with the normal function of the mouth or throat.
Choice C is wrong because coughing while swabbing the throat could contaminate the sample or cause discomfort to the client. The swab should be gently passed along the back area of the throat and tonsils.
Choice D is wrong because swabbing only the anterior tongue would not collect enough cells from the infected area. The swab should reach the back of the throat where bacteria or fungi may grow.
