A client is receiving miotics for the treatment of open-angle glaucoma. The nurse determines that a priority nursing problem is a “Risk for injury and this is based on which etiology?

Increased frequency of lacrimation.

Decreased night vision.

Increased sensitivity to light.

Diminished color perception.

Answer and Explanation

The Correct Answer is B

A) Increased frequency of lacrimation is not typically associated with miotic therapy. Miotics work by constricting the pupil and increasing outflow of aqueous humor to reduce intraocular pressure, but they do not directly affect lacrimation (tear production). Therefore, this option is not the etiology for the “Risk for injury” nursing problem.

B) Decreased night vision is a common side effect of miotic therapy. Miotics constrict the pupil, which can reduce the amount of light entering the eye, leading to impaired night vision or difficulty seeing in low-light conditions. This impaired vision increases the risk of injury, particularly in situations with reduced lighting.

C) Increased sensitivity to light (photophobia) is not typically associated with miotic therapy. Miotics constrict the pupil, which may actually reduce sensitivity to light by decreasing the amount of light entering the eye. Therefore, increased sensitivity to light is not the etiology for the “Risk for injury” nursing problem in this case.

D) Diminished color perception is not a common side effect of miotic therapy. Miotics primarily affect pupil constriction and intraocular pressure but do not typically alter color perception. Therefore, diminished color perception is not the etiology for the “Risk for injury” nursing problem.

Correct Answer is B

Explanation

A) Irritable bowel syndrome: While it's im’ortant to consider the client's me’ical history comprehensively, sumatriptan succinate is primarily contraindicated in clients with a history of coronary artery disease due to its potential vasoconstrictive effects.

B) Coronary artery disease: This is the correct response. Sumatriptan succinate is contraindicated in clients with a history of coronary artery disease or ischemic heart disease due to its potential to cause coronary vasospasm and increase the risk of myocardial ischemia or infarction.

C) Type 2 diabetes mellitus: While it's im’ortant to consider the client's ov’rall medical history, type 2 diabetes mellitus is not specifically contraindicated with sumatriptan succinate use.

D) Seasonal allergic rhinitis: While seasonal allergic rhinitis is relevant to the client's me’ical history, it is not directly related to the contraindications of sumatriptan succinate.

Therefore, the most crucial consideration before administering sumatriptan succinate is to determine if the client has a history of coronary artery disease or ischemic heart disease to avoid potential adverse cardiac effects.

Correct Answer is ["100"]

Explanation

Since the client weighs 90 kg, let’s first convert their weight to pounds to determine the appropriate cefazolin dosage:

Conversion factor: 1 kg = 2.205 pounds

Client weight (pounds) = 90 kg x 2.205 pounds/kg = 198.45 pounds (rounded to two decimals)

Now, comparing the client’s weight (198.45 pounds) to the weight threshold (265.5 pounds):

Client weight is less than the threshold (198.45 pounds < 265.5 pounds).

Therefore, the appropriate dosage is:

Cefazolin 2 grams/100 mL 0.9% normal saline over 1 hour.

The pump rate is determined by the total volume of the IV fluid and the infusion time.

We are not given the specific bag size, but typically these come in 100 mL or 500 mL volumes.

Assuming a 100 mL bag (which aligns with the concentration provided):

Total volume of IV bag: 100 mL

Infusion time: 1 hour

Calculation:

Pump rate (mL/hr) = Total volume (mL) / Infusion time (hr)

Pump rate (mL/hr) = 100 mL / 1 hour = 100 mL/hr

Therefore, the nurse should program the pump to deliver 100 mL/hr.
