A client is telling the nurse in the clinic that he gets a headache after taking sublingual nitroglycerin (Nitrostat) for his angina pain. Which of the following should the nurse instruct the client to do?

Correct Answer: C

Rationale: The correct answer is to instruct the client to lie down in a cool environment and rest after taking sublingual nitroglycerin for angina pain. Headaches are a common side effect of nitroglycerin due to its vasodilatory effects, and resting in a cool environment can help alleviate the headache. Reducing the nitroglycerin dose is not recommended without consulting the healthcare provider as it may compromise the effectiveness of the medication in managing angina. Asking for a strong analgesic is not appropriate since the headache is likely related to the nitroglycerin and not a separate issue requiring a pain reliever. Requesting a different medication should also involve consulting the healthcare provider to ensure an appropriate alternative is prescribed for angina management.

Correct Answer: B

Rationale: The Mantoux skin test, also known as the tuberculin skin test, is a diagnostic tool used to screen for tuberculosis (TB). It involves injecting a small amount of tuberculin under the top layer of the skin on the forearm and then checking for a reaction within 48-72 hours. This test helps identify individuals who have been exposed to the TB bacteria. Sputum culture for acid-fast bacillus (AFB) is used to confirm TB diagnosis in individuals suspected of having active TB. The BCG vaccine is used to prevent severe forms of tuberculosis in high-risk individuals but is not a diagnostic tool. While a chest X-ray can show signs of active TB disease, it is not a primary diagnostic tool for screening purposes.

Correct Answer: C

Rationale: When providing instructions for home oxygen therapy, it is important to ensure safety and proper care. Choices A, B, and D are all essential instructions for the client and family. Choice C, 'Apply petroleum jelly around and inside the nares,' is incorrect. Petroleum jelly should not be used near oxygen sources as it is flammable and can increase the risk of fire hazard. Therefore, this instruction should not be included in the teaching.

Correct Answer: B

Rationale: The priority nursing action in this situation is to evaluate the client's respiratory status. When a client with COPD on oxygen therapy experiences difficulty breathing, the nurse should first assess the client's respiratory status to determine the severity of the situation. Increasing the oxygen flow without proper assessment can be harmful if not clinically indicated. While calling emergency services may eventually be necessary, it should not be the immediate action without assessing the client first. Instructing the client to cough and clear secretions is not appropriate as the nurse needs to evaluate the respiratory status before proceeding with interventions.

Correct Answer: D

Rationale: Encouraging the client to drink eight glasses of water daily is the most appropriate action to help with tenacious bronchial secretions in COPD. Increased fluid intake can help in thinning the mucus, making it easier for the client to cough up and clear secretions. This addresses the client's difficulty in bringing up bronchial secretions. Maintaining a semi-Fowler's position can aid in breathing but does not directly address the issue of clearing secretions. Administering oxygen may be necessary for COPD, but it does not specifically target the tenacious secretions. Selecting a low-salt diet can be helpful in managing COPD in general, but it does not directly address the client's current concern of clearing bronchial secretions.
