Answer to Question 1

3
Latent tuberculosis infection occurs when a person exposed to the mycobacterium has a positive PPD test. This person is without an active clinical picture and has a 10 chance of developing TB if preventive pharmacological treatment is not initiated. The nurse needs pharmacological treatment. Doing nothing could result in active disease. The nurse does not need chest x-rays every 2 months or admission for inpatient treatment.

Answer to Question 2

2
The COPD client's drive to breathe is hypoxia. Increasing the oxygen removes this drive and leads to apnea. Angina occurs because of decreased oxygen to the myocardial tissues. Neither respiratory alkalosis nor metabolic acidosis would occur with the increased oxygen level.
