A client receives a tuberculin (PPD) skin test on Thursday at 1200. The nurse documents on the medication record that the results need to be read:
Sunday morning
Saturday morning
Friday morning
Monday morning
The Correct Answer is A
The tuberculin skin test (TST), also known as the Mantoux test, is used to determine if a person has been infected with the tuberculosis (TB) bacteria. The test involves injecting a small amount of purified protein derivative (PPD) into the skin of the forearm. The injection site is then examined 48 to 72 hours later for a reaction, which is measured in millimeters of induration (swelling).
Choice A reason:
Sunday morning is the correct time to read the test results. Since the test was administered on Thursday at 1200, the 48 to 72-hour window for reading the results would fall between Saturday at 1200 and Monday at 1200. Reading the results on Sunday morning falls within this time frame, making it the appropriate choice.
Choice B reason:
Saturday morning is not the correct time to read the test results. Reading the test results on Saturday morning would be less than 48 hours after the test was administered, which is too early to accurately assess the reaction. The test needs to be read between 48 and 72 hours after administration to ensure accurate results.
Choice C reason:
Friday morning is also not the correct time to read the test results. Reading the test results on Friday morning would be only 24 hours after the test was administered, which is far too early. The immune response to the PPD injection takes time to develop, and reading the test too early can result in a false-negative result.
Choice D reason:
Monday morning is within the acceptable time frame to read the test results, but it is at the very end of the 72-hour window. While it is still technically correct, it is generally recommended to read the test closer to the 48-hour mark to ensure the most accurate results. Therefore, Sunday morning is a better choice.

Correct Answer is B
Explanation
Choice A reason: Effective coughing after medication administration is not specifically required for the use of metered dose inhalers like albuterol and beclomethasone. While coughing can help clear mucus from the airways, it is not a necessary step in the administration of these medications. The primary focus should be on proper inhaler technique to ensure the medication reaches the lungs effectively.
Choice B reason: Rinsing the mouth after beclomethasone administration is crucial. Beclomethasone is an inhaled corticosteroid, and rinsing the mouth helps prevent oral thrush, a common side effect of inhaled steroids. Thrush is a fungal infection that can develop in the mouth and throat due to the residue of the medication. Proper rinsing and spitting out the water can significantly reduce the risk of this infection.
Choice C reason: Using beclomethasone as needed when breathing normally is incorrect. Beclomethasone is a maintenance medication that should be used regularly as prescribed, not on an as-needed basis. It helps control chronic inflammation in the airways and prevent asthma symptoms. Using it only when symptoms are not present would not provide the consistent anti-inflammatory effect needed to manage asthma effectively.
Choice D reason: Taking the beclomethasone first, followed by the albuterol, is incorrect. The correct sequence is to use the albuterol first. Albuterol is a bronchodilator that works quickly to open up the airways, making it easier for the beclomethasone to reach deeper into the lungs and be more effective
Correct Answer is D
Explanation
Choice A reason: Albuterol is a bronchodilator that helps to open up the airways, making it easier to breathe. It is commonly used in the treatment of acute bronchitis, especially if the patient is experiencing wheezing or shortness of breath. Albuterol works by relaxing the muscles around the airways, which helps to relieve symptoms of bronchospasm.
Choice B reason: Guaifenesin is an expectorant that helps to thin and loosen mucus in the airways, making it easier to cough up and clear out. This can be particularly helpful for a patient with a productive cough and green sputum, as it aids in clearing the respiratory passages. Guaifenesin is often used in the management of acute bronchitis to help alleviate symptoms.
Choice C reason: Methylprednisolone is a corticosteroid that helps to reduce inflammation in the airways. It can be beneficial in severe cases of acute bronchitis where there is significant inflammation and swelling of the bronchial tubes. Corticosteroids like methylprednisolone are used to decrease the inflammatory response and improve breathing.
Choice D reason: Dextromethorphan is a cough suppressant that works by affecting the signals in the brain that trigger the cough reflex. However, in the case of acute bronchitis with a productive cough, suppressing the cough can be counterproductive. The goal is to clear the mucus from the airways, and suppressing the cough can lead to mucus retention and potentially worsen the condition. Therefore, the use of a cough suppressant like dextromethorphan is not recommended in this scenario.
