A patient with tuberculosis is started on isoniazid (INH). What should the nurse monitor for?

Correct Answer: A

Rationale: The correct answer is A: Signs of peripheral neuropathy. Isoniazid can cause peripheral neuropathy due to vitamin B6 deficiency. The nurse should monitor for numbness, tingling, or weakness in extremities. Choices B, C, and D are incorrect because isoniazid does not typically cause hearing loss, visual disturbances, or hair thinning.

Correct Answer: B

Rationale: The correct answer is B because in a critical situation like severe respiratory distress, immediate actions are crucial. Asking focused questions about the current episode will provide essential information for quick decision-making and interventions. It helps in assessing the severity of the distress, identifying potential causes, and determining the appropriate initial treatment. Obtaining a comprehensive health history (choice A) can be important but not urgent in this acute situation. Delaying assessment for pulmonary function tests (choice C) can be detrimental as it can delay necessary interventions. Checking for allergies before treatment (choice D) is important but not the priority when the patient is in severe distress.

Correct Answer: C

Rationale: The correct answer is C: Provide low-flow oxygen therapy. In COPD, hypoxemia (low PaO2) is the primary concern. Administering oxygen can help improve oxygenation and prevent further complications. Bronchodilators (choice A) may be indicated for symptom relief but not the priority. Pursed-lip breathing (choice B) can help with exhalation and symptom management but does not address the immediate hypoxemia. Assessing the patient's level of consciousness (choice D) is important but providing oxygen to improve oxygenation takes precedence in this case.

Correct Answer: C

Rationale: Rationale: Choice C indicates the need for further teaching because forcefully exhaling after inhaling the medication can reduce the amount of medication reaching the lungs. The correct technique is to hold the breath for 10 seconds to allow the medication to be absorbed effectively. Choices A, B, and D are all correct techniques for using a metered-dose inhaler and do not indicate the need for further teaching.

Correct Answer: A

Rationale: The correct answer is A: Administer supplemental oxygen. This is the priority intervention for a patient with a suspected pulmonary embolism because it helps improve oxygenation and prevents further hypoxia. Oxygen therapy is crucial in stabilizing the patient's condition and should be initiated promptly. Summary of other choices: B: Notifying the healthcare provider is important, but administering oxygen takes precedence due to the immediate need for oxygenation. C: While a CT scan is important for confirming the diagnosis, providing oxygen is more urgent to address the patient's hypoxia. D: Starting anticoagulant therapy is a critical treatment for pulmonary embolism, but ensuring oxygenation is the immediate priority to stabilize the patient's condition.
