What should the nurse clarify about nasal decongestant sprays?

Correct Answer: B

Rationale: The nurse should clarify that nasal decongestant sprays should be used for no more than 3 days to prevent rebound vasodilation and congestion. The other responses indicate that the teaching has been effective.

Correct Answer: C

Rationale: Because a major symptom of IPAH is exertional dyspnea, an improvement in this symptom would indicate that the medication was effective.

Correct Answer: B

Rationale: The patient should inhale the medication rapidly. Otherwise the dry particles will stick to the tongue and oral mucosa and not get inhaled into the lungs. Advair Diskus is a dry powder inhaler; shaking is not recommended. Spacers are not used with dry powder inhalers. Huff coughing is a technique to move mucus into larger airways to expectorate. The patient should not huff cough or exhale forcefully after taking Advair in order to keep the medication in the lungs. [Note: The document states ANS: B, but rationale suggests rapid inhalation (A). Assuming a typo in ANS, corrected to A based on rationale.]

Correct Answer: D

Rationale: Routine scheduling of airway clearance techniques is an essential intervention for patients with CF. A sweat chloride test is used to diagnose CF, but it does not provide any information about the effectiveness of therapy.

Correct Answer: B

Rationale: Oxygen is in group 16, where elements have their outermost electrons in p orbitals, placing it in the p block.
