The nurse is assessing the eyes of a client who just received mydriatic eye drops. Which physiological function of the eye will not respond during the therapeutic period after administration of the eye drops?

Pupillary constriction.

Refraction.

Eye convergence.

Accommodation.

Answer and Explanation

The Correct Answer is A

A. Pupillary constriction: Mydriatic eye drops are designed to dilate the pupils, which means they inhibit pupillary constriction. During the therapeutic period after administration, the pupil remains dilated and does not constrict in response to light or other stimuli.
B. Refraction: Refraction, the bending of light as it passes through the eye's lens and cornea, is not directly affected by mydriatic eye drops. The process of focusing light onto the retina is still functional even when the pupils are dilated.
C. Eye convergence: Eye convergence, the inward movement of both eyes toward each other to focus on a close object, remains functional during mydriasis. Mydriatic drops do not typically impair this ability.
D. Accommodation: Accommodation, the eye's ability to change the focus from distant to near objects, is affected by mydriatic drops. These medications paralyze the ciliary muscles responsible for accommodation, making it difficult to focus on near objects during the period of dilation.

Correct Answer is D

Explanation

A. Pulse rate:
While monitoring the pulse rate is important for assessing overall cardiovascular function, it is not the most immediate concern when a client becomes lethargic after receiving an opioid. Opioids are known to potentially cause respiratory depression, which is a more critical issue to address first.
B. Blood pressure:
Blood pressure changes can occur with opioid use, but in the context of sudden lethargy, the primary concern is to check for respiratory depression. This condition can lead to significant complications and requires immediate attention.
C. Temperature:
Temperature monitoring is important for identifying infection or other issues, but it is not the most relevant vital sign to assess immediately after noticing lethargy from opioid administration. Respiratory rate is more directly affected by opioids.
D. Respiratory rate:
Opioids can cause respiratory depression, which can lead to lethargy and other serious complications. Assessing the respiratory rate first is crucial to determine if the client is experiencing slowed or irregular breathing, which may require immediate intervention such as administering naloxone or providing supplemental oxygen.

A. Before meals to prevent hyperglycemia. B. When unable to eat during sick days. C. When signs of severe hypoglycemia occur. D. At the onset of signs of diabetic ketoacidosis.

Correct Answer is C

Explanation

A. Before meals to prevent hyperglycemia: Glucagon is not used to prevent hyperglycemia. Instead, it is used in emergency situations to address severe hypoglycemia. Preventing hyperglycemia is typically managed with insulin and other diabetes management strategies, not glucagon.
B. When unable to eat during sick days: While it is important to manage blood glucose levels when unable to eat, glucagon is specifically used for severe hypoglycemia rather than during periods of illness where eating is difficult. During sick days, other measures, such as adjusting insulin or seeking medical advice, are more appropriate.
C. When signs of severe hypoglycemia occur: This is the correct instruction. Glucagon is an emergency treatment used to rapidly raise blood glucose levels in cases of severe hypoglycemia where the person is unconscious or unable to take oral glucose. Recognizing and administering glucagon during severe hypoglycemic episodes is crucial for preventing complications.
D. At the onset of signs of diabetic ketoacidosis: Glucagon is not used to treat diabetic ketoacidosis (DKA). DKA is managed with insulin, fluids, and electrolytes. Glucagon is specifically for severe hypoglycemia and is not indicated for DKA.
