Which assessment finding indicates to the practical nurse that a Venturi face mask is producing the desired effect?

Increased oxygen saturation.

Increased cough productivity.

Decreased cough frequency.

Decreased breath sounds.

Answer and Explanation

The Correct Answer is A

A. Increased oxygen saturation indicates that the Venturi face mask is effectively delivering the specified concentration of oxygen. This is the primary goal of using a Venturi mask, which provides precise oxygen delivery to improve oxygen saturation levels.
B. Increased cough productivity is not a direct indicator of the effectiveness of a Venturi face mask. The mask's purpose is to deliver oxygen, not to alter cough patterns.
C. Decreased cough frequency is unrelated to the function of the Venturi face mask. The mask's effectiveness is measured by oxygen delivery rather than changes in cough frequency.
D. Decreased breath sounds are not a direct measure of the effectiveness of a Venturi face mask. Breath sounds could indicate other respiratory issues but do not specifically reflect the effectiveness of oxygen therapy.

Correct Answer is D

Explanation

A. Administering half of the missed dose is not generally recommended because it could lead to inconsistent drug levels and potential for breakthrough seizures. The standard practice is to follow the dosing schedule unless otherwise instructed by the healthcare provider.
B. Giving the missed dose with the next scheduled dose may lead to double dosing and could increase the risk of side effects or toxicity. The missed dose should be addressed as soon as possible but not in combination with the next dose.
C. Withholding the missed dose unless seizure activity occurs could put the client at risk for seizures. Anticonvulsants should be administered as per the prescribed schedule to maintain therapeutic drug levels and prevent seizures.
D. Administering the missed dose as soon as possible is the correct approach, following standard guidelines for missed medications. The missed dose should be given promptly unless it is close to the time of the next dose, in which case the next dose should be given as scheduled.

A. Plan to bring her back to the doctor's office for another urine test. B. Refill the antibiotic if symptoms persist after finishing the prescription. C. Make certain the young girl wipes from back to front after each void. D. Give the antibiotic until she no longer complains of burning.

Correct Answer is A

Explanation

A. Follow-up urine tests are essential to ensure that the UTI is fully resolved and to check for any potential recurrence or complications.
B. The full course of antibiotics must be completed even if symptoms improve. Refiling antibiotics should only be done based on a healthcare provider's recommendation, not symptom persistence.
C. For females, the correct wiping technique is from front to back to avoid introducing bacteria from the anus to the urethra, so this statement is incorrect.
D. Antibiotics should be taken for the entire prescribed duration to completely eradicate the infection, not just until symptoms improve.
