B	Respiratory alkalosis, uncompensated
C	Metabolic acidosis, partially compensated

A	Diabetes mellitus
B	Glaucoma
C	Emphysema
D	Hypothyroidism

Question 2 Explanation:

Cyclobenzaprine (Flexeril) has anticholinergic activity, to which elderly patients are especially sensitive. Cyclobenzaprine should be prescribed with great caution and monitoring to patients with conditions that are likely to be exacerbated by anticholinergic activity, such as glaucoma.

Question 3

The nurse recognizes the following symptom as a result of a phenytoin blood level study that reveals a level of 35 mcg/mL in the client:

A	Tachycardia
B	Slurred speech
C	Nystagmus
D	No symptoms, because this is a normal therapeutic level

Question 3 Explanation:

Normal therapeutic ranges for adults taking phenytoin are between 10-20 mcg/mL. One symptom of a patient that is experiencing levels higher than this range is slurred speech.

A	Dizziness
B	Worsening renal function

Question 4 Explanation:

Dizziness does not indicate a hypersensitivity to Allopurinol. Rash, fever, and worsening renal function do indicate hypersensitivity to Allopurinol, as does acute hepatocellular injury, leukocytosis, and eosinophilia.

D	Placing the client in a left-side lying position with the head lower than the feet

Question 5 Explanation:

A patient receiving parenteral nutrition experiencing shoulder pain, sudden shortness of breath, and absence of breath sounds on affected side may have a pneumothorax. Pneumothorax may resolve itself, but if not, the nurse should insert a chest tube.
