The nurse enters a client's room with a pulse oximetry machine and tells the client that the health care provider (HCP) has prescribed continuous oxygen saturation readings. The client's facial expression changes to one of apprehension. The nurse can alleviate the client's anxiety by providing which information about pulse oximetry?
It causes only mild discomfort at the site the probe is placed.
It requires insertion of only a small catheter in one nostril.
It is painless and safe.
It has an alarm to signal dangerous drops in oxygen levels.
The Correct Answer is C
A. It causes only mild discomfort at the site the probe is placed: Pulse oximetry is noninvasive and typically does not cause any discomfort unless the probe is left on too long or applied too tightly.
B. It requires insertion of only a small catheter in one nostril: This refers to oxygen delivery via nasal cannula, not pulse oximetry. Mentioning catheter insertion may increase the client’s apprehension, as it implies an invasive procedure, which pulse oximetry is not.
C. It is painless and safe: Pulse oximetry is a noninvasive method that uses light to measure oxygen saturation through a fingertip or earlobe, making it both painless and very safe for continuous monitoring.
D. It has an alarm to signal dangerous drops in oxygen levels: While accurate, focusing on alarms may heighten the client’s anxiety by implying that dangerous events are expected. This information is more relevant after the client is reassured about the procedure’s safety.

Correct Answer is A
Explanation
A. Antihistamine:Antihistamines are the first-line treatment for allergic reactions such as itchy, watery eyes, sneezing, and coughing caused by allergens like grass pollen. They block histamine, the chemical responsible for allergic symptoms, providing effective relief in seasonal allergies.
B. Antitussive:Antitussives suppress coughing and are used for dry, nonproductive coughs. They do not address the underlying allergic reaction or associated symptoms like sneezing and itchy eyes, making them inappropriate for this case.
C. Decongestant:Decongestants relieve nasal congestion by constricting blood vessels in the nasal mucosa. While they may help with stuffiness, they do not treat the histamine-mediated symptoms such as watery eyes or sneezing effectively.
D. Expectorant:Expectorants thin mucus to help with productive coughs. They are not helpful in treating allergic reactions and will not relieve the patient's symptoms caused by grass allergy exposure.
Correct Answer is A
Explanation
A. Vitamin K:Vitamin K is the antidote for warfarin overdose. Warfarin inhibits vitamin K-dependent clotting factors, and administering vitamin K reverses this effect by promoting the synthesis of clotting factors to control bleeding.
B. Magnesium sulfate:Magnesium sulfate is used to treat conditions such as torsades de pointes and eclampsia but has no role in reversing the anticoagulant effects of warfarin. It does not impact coagulation pathways or vitamin K levels.
C. Flumazenil:Flumazenil is an antidote for benzodiazepine overdose. It acts by antagonizing the effects of drugs like diazepam and lorazepam but has no effect on warfarin or anticoagulation reversal.
D. Protamine sulfate:Protamine sulfate is the antidote for heparin and low-molecular-weight heparin overdose, not warfarin. It neutralizes heparin's anticoagulant properties but does not interact with vitamin K or affect warfarin action.
