Correct Answer is A

Explanation

A. Albumin is a protein that is produced by the liver and is a good indicator of nutritional status. TPN is intended to provide adequate nutrition to the patient, so an increase in albumin levels would indicate that the treatment is effective.
B. Calcium levels are not directly related to the effectiveness of TPN. Calcium levels can be affected by a variety of factors and are not a specific marker for the effectiveness of TPN.
C. Hematocrit (Hct) measures the percentage of red blood cells in the blood. It is not directly related to the effectiveness of TPN.
D. White blood cell count (WBC) is a marker of immune function and is not directly related to the effectiveness of TPN.

A. Pupillary dilation B. Elevated heart rate C. Hypertension D. Tachypnea

Correct Answer is B

Explanation

A. Fentanyl, an opioid, typically causes pupillary constriction, not dilation. This is known as miosis.
B. Fentanyl can cause bradycardia or tachycardia, but tachycardia is more common in acute toxicity.
C. Fentanyl is more likely to cause hypotension (low blood pressure) rather than hypertension (high blood pressure).
D. Fentanyl can cause respiratory depression, leading to hypoventilation and possibly bradypnea or apnea, but tachypnea (rapid breathing) is less likely to occur as a direct effect of fentanyl toxicity.
