A nurse is performing blood glucose monitoring on a client. Which of the following actions should the nurse take?
Position the client's finger above their heart.
Apply sterile gloves prior to performing the test.
Puncture the side of the client's finger.
Milk the finger site.
The Correct Answer is C
A. Position the client's finger above their heart: The finger should be positioned below the level of the heart to encourage blood flow, making it easier to obtain a sufficient blood sample for testing. Elevating the finger would decrease blood flow and make collection more difficult.
B. Apply sterile gloves prior to performing the test: Clean, non-sterile gloves are sufficient for routine blood glucose monitoring. Sterile gloves are not necessary unless performing procedures that require a sterile environment, such as surgery or central line dressing changes.
C. Puncture the side of the client's finger: The sides of the fingertips have fewer nerve endings compared to the pads, making the procedure less painful. Additionally, puncturing the side helps promote better blood flow and reduces the risk of bruising and soreness.
D. Milk the finger site: Milking or squeezing the finger excessively can cause hemolysis or contamination of the blood sample with tissue fluid, leading to inaccurate glucose readings. Gentle pressure may be used if needed, but forceful milking should be avoided.

- 3-month history of unplanned weight loss, increased sweating, heat intolerance, fatigue, and difficulty sleeping: These symptoms are classic for hyperthyroidism and suggest worsening metabolic imbalance. They require follow-up because untreated hyperthyroidism can lead to serious complications like thyroid storm.
- Reports last menstrual period was 3 months ago: Amenorrhea or menstrual irregularities are common in hyperthyroidism due to hormonal disruption. This finding supports the diagnosis and needs follow-up for endocrine and reproductive health management.
- Exophthalmos noted: Exophthalmos, or bulging eyes, is associated with Graves' disease and indicates autoimmune involvement affecting the orbital tissues. It can lead to complications like corneal ulceration or vision loss if severe and thus requires ophthalmologic evaluation.
- Goiter visualized on neck: A visible goiter reflects thyroid gland enlargement, often due to hyperstimulation from excess thyroid hormones. It requires ongoing monitoring to assess for airway compromise, dysphagia, or further gland enlargement.
- Client’s partner reports irritability and anxiety: Behavioral and mood changes like irritability and anxiety are manifestations of hyperthyroidism affecting neurological function. Persistent symptoms can impair quality of life and must be addressed as part of comprehensive treatment planning.
Correct Answer is ["0.25"]
Explanation
Desired dose = 0.25 mg
Available concentration = 1 mg/mL
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 0.25 mg / 1 mg/mL
= 0.25 mL
