A nurse is preparing to administer methylphenidate 7.5 mg PO to a school-age child who has ADHD. The amount available is methylphenidate oral solution 5 mg/5 mL. How many mL of the medication should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)

A. Auscultate the client's lung sounds: While lung sounds are important to assess in clients with heart failure, auscultating lung sounds is not directly required before administering digoxin. The immediate concern with digoxin is its effect on heart rate and rhythm.

B. Check the client's weight: Monitoring weight is important in heart failure management to assess fluid retention, but weight measurement is not necessary immediately prior to administering a dose of digoxin.

C. Check the client's apical pulse: Before giving digoxin, it is critical to assess the client's apical pulse for one full minute. If the pulse is below a specified rate (60 beats/min for adults), the dose may need to be withheld and the provider notified due to the risk of digoxin-induced bradycardia.

D. Obtain the client's oxygen saturation: Oxygen saturation is important in evaluating respiratory function, but it is not a priority action before administering digoxin. The primary safety check is heart rate assessment.

A. "If I have a health care proxy, then I do not need to have a living will.": A health care proxy and a living will serve different purposes. A living will outlines specific treatment preferences, while a health care proxy designates someone to make decisions. Having one does not eliminate the benefit or need for the other.

B. "My health care proxy designee is not able to sign a consent form on my behalf.": The designee named in a health care proxy is specifically authorized to make healthcare decisions, including signing consent forms, if the client becomes unable to do so themselves.

C. "I do not need to name a relative as my designee in my health care proxy.": A client can choose any competent adult they trust to act as their healthcare proxy; it does not have to be a relative. This flexibility allows clients to select someone they believe will best honor their wishes.

D. "Once my health care proxy is in place, I relinquish my right to make my own decisions.": Having a health care proxy does not remove the client's decision-making rights. The proxy only takes effect if the client becomes unable to make or communicate their own healthcare decisions.
