A nurse is preparing to obtain a postprandial blood glucose level from a client who has diabetes mellitus. Which of the following actions should the nurse take?
Clean the client's finger with hexachlorophene.
Apply the first drop of blood to the test strip.
Hold the client's finger in a dependent position.
Prick the central tip of the client's finger.
The Correct Answer is C
A. Clean the client's finger with hexachlorophene: Hexachlorophene is not recommended for cleaning the skin before blood glucose testing; a mild soap and water or an alcohol swab is typically used.
B. Apply the first drop of blood to the test strip: The first drop of blood is often not used due to potential contamination; the nurse should usually wipe away the first drop and use the second one.
C. Hold the client's finger in a dependent position: This is correct as holding the finger downward can help increase blood flow to the fingertip, facilitating easier blood collection.
D. Prick the central tip of the client's finger: Pricking the central tip can be painful; the sides of the fingertip are preferred for less discomfort and to avoid nerve endings.

Correct Answer is C
Explanation
A. The medication reduces the rate at which the kidneys filter waste: This is incorrect as oxybutynin does not affect kidney function or the rate at which kidneys filter waste.
B. The medication decreases the sensitivity of the urethral sphincter: This is incorrect because oxybutynin primarily affects bladder muscle contraction, not the sensitivity of the urethral sphincter.
C. The medication prevents the bladder muscles from involuntarily contracting: This is correct as oxybutynin is an anticholinergic medication that reduces involuntary bladder contractions, leading to less frequent urination.
D. The medication blocks the nervous system impulse to produce urine: This is incorrect because oxybutynin works by blocking the action of acetylcholine in the bladder, not by blocking impulses to produce urine.
Correct Answer is B
Explanation
A. Glaucoma: Propranolol is not contraindicated in clients with glaucoma. It may, however, need to be used cautiously if the client has narrow-angle glaucoma due to potential systemic effects.
B. Asthma: This is correct as propranolol, a non-selective beta-blocker, can exacerbate asthma by causing bronchoconstriction, making it contraindicated in individuals with asthma.
C. Migraine headaches: Propranolol is often used to prevent migraine headaches and is not contraindicated in this condition. It is actually considered an effective treatment for migraine prophylaxis.
D. Irritable bowel syndrome: Propranolol is not contraindicated in irritable bowel syndrome. There are no specific concerns regarding propranolol's use with this condition.
