A client receives a prescription for dextrose 5% in water 500 mL IV to be infused over 4 hours. The IV administration set delivers 15 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["31"]

To find out how many gtt/min the nurse should regulate the infusion;

We can use the following formula:

Flow rate (gtt/min) = Total volume (mL) / Time (min) × Drop factor (gtt/mL)

Given:

Total volume = 500 mL

Time = 4 hours = 240 minutes (since 1 hour = 60 minutes)

Drop factor = 15 gtt/mL

Substituting the given values into the formula:

Flow rate (gtt/min) =500 mL/240 min ×15 gtt/mL

After performing the calculation, we find that the flow rate equals 31.25 gtt/min.

So, the nurse should regulate the infusion to 31 gtt/min (rounded to the nearest whole number).

Correct Answer is B

Explanation

A) Diminished renal output:
Diminished renal output could be a potential concern with cefoxitin administration, as it is primarily excreted by the kidneys. However, it is not specifically related to the client’s allergy to penicillin. While it warrants monitoring, it is not the most critical finding to report in this context.

B) Pruritis and macular rash:
The development of pruritis (itchiness) and a macular rash (flat, discolored skin lesions) following the administration of cefoxitin in a client with a documented allergy to penicillin is a significant finding. It suggests a possible allergic reaction to cefoxitin, which belongs to the cephalosporin class of antibiotics. Cross-reactivity between penicillin and cephalosporins is well-documented, with some cephalosporins having a higher risk of allergic reactions in individuals with penicillin allergy. Therefore, pruritis and rash in this context may indicate an allergic response, and it is crucial to report this finding promptly to the healthcare provider for further evaluation and management.

C) Vomiting and diarrhea:
While gastrointestinal symptoms such as vomiting and diarrhea can occur as adverse effects of cefoxitin, they are not specific to an allergic reaction and may occur with various medications. While it is essential to monitor for these symptoms, they are not the most important findings to report in the context of a known penicillin allergy.

D) Vaginal discharge:
Vaginal discharge is not typically associated with an allergic reaction to cefoxitin. While changes in vaginal discharge may be clinically relevant in certain contexts, such as indicating a possible yeast infection or bacterial vaginosis, it is not directly related to the client’s allergy to penicillin or the administration of cefoxitin.

A. Monitor blood pressure. B. Assess urine output. C. Obtain daily weights. D. Perform a bladder scan.

Correct Answer is A

Explanation

A) Monitor blood pressure:
This is the correct answer. Tamsulosin, like other alpha-blockers, can cause orthostatic hypotension, which is characterized by a sudden drop in blood pressure when transitioning from lying down or sitting to standing. Monitoring blood pressure, particularly when initiating therapy or adjusting the dosage, helps detect and manage hypotensive episodes. Clients should be advised to change positions slowly to minimize the risk of falls or injury.

B) Assess urine output:
While tamsulosin can affect urinary function by relaxing smooth muscle in the prostate and bladder neck, it typically does not significantly impact urine output. Therefore, monitoring urine output is not a primary intervention for assessing adverse reactions to tamsulosin.

C) Obtain daily weights:
Tamsulosin is not typically associated with significant fluid retention or changes in body weight. Daily weight measurements are more relevant for assessing fluid balance in clients receiving medications such as diuretics or those with conditions like heart failure or renal disease.

D) Perform a bladder scan:
Tamsulosin does not directly affect bladder volume or urinary retention to the extent that necessitates routine bladder scanning. Bladder scans are typically performed in clients with suspected urinary retention or those at risk for urinary retention due to conditions like BPH, but it's not a standard intervention for monitoring adverse reactions to tamsulosin.
