A nurse is preparing to administer morphine 30 mg oral suspension to a client. The amount available is morphine 100 mg/5mL oral solution. How many mi 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. "I should expect my tears to turn a red color after using the eye drops.": Timolol does not cause red discoloration of tears. Redness of the eye may indicate irritation, allergy, or another adverse effect, so the client should report persistent redness rather than expect it as normal.

B. "I will put pressure on the corner of my eye after using the eye drops.": Applying gentle pressure to the nasolacrimal duct (inner corner of the eye) after instilling timolol reduces systemic absorption and potential systemic side effects, such as bradycardia or hypotension. This technique demonstrates proper administration and understanding of safety precautions.

C. "The drops should be placed in the center of my eye.": Eye drops should be instilled into the lower conjunctival sac, not directly onto the center of the cornea, to reduce irritation and maximize absorption. Placing drops on the cornea can cause discomfort and reduce effectiveness.

D. "These drops will improve my cloudy vision.": Timolol lowers intraocular pressure but does not restore vision or improve cloudiness caused by glaucoma. The goal of therapy is to prevent progression of vision loss, not to reverse existing damage.

A. Abdomen: The abdomen is typically used for subcutaneous injections, such as insulin or heparin, due to its fatty tissue. It is not ideal for intradermal injections, which require a thin layer of skin to allow for proper absorption and observation of a wheal.

B. Deltoid: The deltoid muscle is commonly used for intramuscular injections, not intradermal ones. Using this site for intradermal injections could result in the medication being deposited too deeply, affecting absorption and test accuracy.

C. Back of the upper arm: The inner surface of the forearm or the back of the upper arm is the preferred site for intradermal injections, such as tuberculosis or allergy testing. This area has thin skin, minimal subcutaneous fat, and allows for easy visualization of the wheal and monitoring for reactions.

D. Upper back: While the upper back has subcutaneous tissue, it is not commonly used for intradermal injections because it is less accessible for observation and assessment of local reactions. Proper site selection is important for safety and effectiveness.
