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 A

Explanation

A. Body mass index (BMI):
Monitoring BMI is crucial for assessing the effectiveness of orlistat, as it is a medication specifically used to assist with weight management. Changes in BMI will provide a clear indication of how well the medication is working in helping the client lose or maintain weight.
B. Daily calorie count:
While tracking daily calorie intake can provide insight into the client’s adherence to dietary recommendations, it is not a direct measure of the effectiveness of orlistat. The medication's impact is better evaluated through changes in body weight and BMI rather than daily calorie consumption alone.
C. Depression screening:
Although managing weight can impact mental health, depression screening is not directly related to assessing the effectiveness of orlistat. The primary focus should be on evaluating weight changes and BMI, not mental health assessments.
D. Serum protein levels:
Orlistat can affect the absorption of fat-soluble vitamins, but monitoring serum protein levels is not a direct measure of the medication’s effectiveness. Instead, changes in body weight and BMI are more relevant for evaluating the impact of orlistat on weight management

A. Advise the pharmacy of the need to deliver a vial of heparin to the nursing unit immediately. B. Request a prescription to change the route of administration and use the available heparin. C. Calculate and administer the equivalent dose of the available low molecular weight heparin. D. Dilute the available heparin in 250 mL of normal saline solution prior to IV administration.

Correct Answer is A

Explanation

A. Advise the pharmacy of the need to deliver a vial of heparin to the nursing unit immediately: This is the appropriate action. The prescription is for standard heparin, which is different from low molecular weight heparin (LMWH) in both its formulation and use. Standard heparin must be administered intravenously and requires a different preparation than LMWH, which is typically administered subcutaneously. The nurse should request the correct form of heparin (standard heparin) to ensure the client receives the prescribed medication safely and effectively.
B. Request a prescription to change the route of administration and use the available heparin: Changing the route of administration would be inappropriate without proper authorization from the healthcare provider. Low molecular weight heparin is not used for intravenous administration in this context, so this option does not address the need for the correct medication form.
C. Calculate and administer the equivalent dose of the available low molecular weight heparin: Low molecular weight heparin and standard heparin are not interchangeable, and the dosing and administration routes are different. Attempting to convert the dose of LMWH to standard heparin is not advisable without proper guidance, as this could lead to incorrect dosing and potential harm.
D. Dilute the available heparin in 250 mL of normal saline solution prior to IV administration: This is not applicable to low molecular weight heparin. Standard heparin, if available, may require dilution for IV administration, but LMWH is not used for IV administration and should not be substituted in this manner
