A woman visits a health center requesting oral contraceptives. Which laboratory test is most important for the nurse to assess before the patient begins oral contraceptive therapy?
Vaginal cultures
Complete blood count
Serum potassium level
Pregnancy test
The Correct Answer is C
Choice A reason: Vaginal cultures are not necessary for oral contraceptive therapy. They are used to diagnose infections such as bacterial vaginosis, yeast infection, or sexually transmitted diseases.
Choice B reason: Complete blood count is not essential for oral contraceptive therapy. It is used to measure the number and types of blood cells, such as red blood cells, white blood cells, and platelets.
Choice C reason: Serum potassium level is the most important laboratory test for oral contraceptive therapy. This is because some oral contraceptives can increase the risk of hyperkalemia, which is a high level of potassium in the blood. Hyperkalemia can cause serious complications such as cardiac arrhythmias, muscle weakness, and paralysis.
Choice D reason: Pregnancy test is not a laboratory test, but a urine test. It is important to rule out pregnancy before starting oral contraceptive therapy, but it is not the most important test for the nurse to assess.

Correct Answer is B
Explanation
Choice A reason: This is incorrect because hypoxia does not cause an increased need for insulin, but rather a decreased utilization of glucose by the cells. Hypoxia can also impair the secretion of insulin by the pancreas.
Choice B reason: This is correct because corticosteroids are known to cause hyperglycemia by stimulating gluconeogenesis, inhibiting glucose uptake, and increasing insulin resistance. The patient may need to adjust his insulin dose or switch to oral antidiabetic agents while on corticosteroid therapy.
Choice C reason: This is incorrect because antibiotics do not cause an increase in glucose levels, unless they are combined with other drugs that affect glucose metabolism, such as sulfonamides or fluoroquinolones.
Choice D reason: This is incorrect because type 2 diabetes does not convert to type 1 diabetes, as they are different types of diabetes with different causes and mechanisms. Type 1 diabetes is caused by autoimmune destruction of the beta cells of the pancreas, resulting in absolute insulin deficiency. Type 2 diabetes is caused by insulin resistance and relative insulin deficiency.
Correct Answer is B
Explanation
Choice A reason: Benzonatate is not the correct answer. Benzonatate is a cough suppressant that works by numbing the throat and lungs. It does not help in the removal of mucus.
Choice B reason: Guaifenesin is the correct answer. Guaifenesin is an expectorant that works by thinning and loosening the mucus in the airways. It helps in the removal of mucus by making it easier to cough up.
Choice C reason: Diphenhydramine is not the correct answer. Diphenhydramine is an antihistamine that works by blocking the effects of histamine, a chemical that causes allergy symptoms. It does not help in the removal of mucus.
Choice D reason: Dextromethorphan is not the correct answer. Dextromethorphan is a cough suppressant that works by affecting the signals in the brain that trigger the cough reflex. It does not help in the removal of mucus.
