Answer and Explanation

The Correct Answer is A

A. Urine output 20 mL/hr: Oliguria, or low urine output (less than 30 mL/hr), is a common sign of dehydration.
B. Bradycardia: Dehydration typically causes tachycardia (increased heart rate) as the body compensates for decreased blood volume.
C. Sodium 142 mEq/L: A sodium level of 142 mEq/L is within the normal range (135-145 mEq/L) and does not indicate dehydration.
D. Cool skin: Dehydration usually results in warm, dry skin due to decreased perfusion and sweating.

Correct Answer is D

Explanation

A. The spacer increases the amount of medication delivered to the oropharynx. The spacer actually reduces the amount of medication deposited in the oropharynx, directing more to the lungs.
B. Inhale rapidly when using the spacer with the MDI. The correct technique is to inhale slowly and deeply to ensure the medication reaches the lungs.
C. Cover exhalation slots of the spacer with lips when inhaling. The lips should form a seal around the mouthpiece, but covering exhalation slots is not necessary.
D. The spacer increases the amount of medication delivered to the lungs. This is the primary benefit of using a spacer, making it the correct answer.

A. Parasites B. Blood C. Bacteria D. Fat

Correct Answer is B

Explanation

A. Parasites: The stool guaiac test does not detect parasites; it is used to detect blood.
B. Blood: The stool guaiac test (or fecal occult blood test) detects hidden (occult) blood in the stool.
C. Bacteria: The stool guaiac test does not identify bacteria; stool cultures are used for that purpose.
