Before inserting an indwelling urinary catheter, which information about the patient is most important for the nurse to obtain?

Color, clarity, and odor of urine.

Patient’s ability to increase fluid intake.

Patient allergies to antiseptic solutions.

Previous history of urinary tract infections.

Answer and Explanation

The Correct Answer is C

Choice A rationale
While the color, clarity, and odor of urine can provide important information about a patient’s overall health and hydration status, it is not the most crucial information to obtain before inserting an indwelling urinary catheter.
Choice B rationale
The patient’s ability to increase fluid intake can be important in managing various health conditions, but it is not the most important information to obtain before this procedure.
Choice C rationale
Knowing if a patient has allergies to antiseptic solutions is crucial before inserting an indwelling urinary catheter. Using an antiseptic solution that a patient is allergic to can lead to serious complications.
Choice D rationale
While a previous history of urinary tract infections can inform the care and management of a patient with an indwelling urinary catheter, it is not the most important information to obtain before the procedure.

Correct Answer is D

Explanation

Choice A rationale
Administering the medication at 1000, 1600, 2200, and 0400 would not be the best schedule because it does not evenly distribute the doses throughout the day. This could lead to periods of subtherapeutic medication levels and periods of potential toxicity.
Choice B rationale
Administering the medication with meals and a bedtime snack is not the best schedule for this medication. While some medications need to be administered with food, there is no indication

that this medication needs to be. Furthermore, this schedule could lead to uneven distribution of the medication throughout the day.
Choice C rationale
Giving the medication in equally divided doses during waking hours is not the best schedule because it does not take into account the half-life of the medication or the patient’s sleep schedule. This could lead to subtherapeutic levels of the medication during the night.
Choice D rationale
Administering the medication at 0800, 1200, 1600, and 2000 is the best schedule for this medication. It evenly distributes the doses throughout the day, which can help maintain a therapeutic level of the medication and reduce the risk of toxicity.

A. Productive cough B. Respiratory rate of 28 breaths/minute C. Oxygen saturation of 90% on room air D. Heart rate of 101 beats/minute E. Capillary refill of 4 seconds F. Blood pressure of 145/89 mm Hg

Correct Answer is ["B","C","D"]

Explanation

Choice A rationale
A productive cough is not a specific indicator of hypoxia. It could be a symptom of many conditions, including a common cold, flu, or other respiratory tract infections.
Choice B rationale

A respiratory rate of 28 breaths/minute is higher than the normal range (12-20 breaths/minute for adults), indicating that the patient may be trying to increase oxygen intake and eliminate carbon dioxide due to hypoxia.
Choice C rationale
An oxygen saturation of 90% on room air is lower than the normal range (95%-100%). This indicates that the patient’s blood is not carrying as much oxygen as it should, which is a sign of hypoxia.
Choice D rationale
A heart rate of 101 beats/minute is higher than the normal range (60-100 beats/minute for adults). This could be a response to hypoxia as the body tries to deliver more oxygen to the tissues.
Choice E rationale
A capillary refill of 4 seconds is slightly longer than the normal range (less than 2 seconds). While this could indicate poor peripheral circulation, it is not a specific or direct indicator of hypoxia.
Choice F rationale
A blood pressure of 145/89 mm Hg is higher than the normal range (less than 120/80 mm Hg). While hypertension could be related to many factors, it is not a specific indicator of hypoxia.
