The prescription reads for guaifenesin 400 mg PO every 4 hours as needed for congestion. Using the label below, how many mL will the nurse administer to the client? Enter a numeric value only. Answer to the nearest whole mL.

A) Lying flat on the back: Positioning the client flat on their back is not the most effective position for administering a rectal suppository. The correct position allows for easier insertion and proper absorption of the medication. Lying flat on the back may make it difficult for the nurse to administer the suppository in the correct manner.

B) Lying flat on the stomach: Lying flat on the stomach is not recommended for the administration of a rectal suppository, as it can be uncomfortable for the client and can impede the ability to access the rectal area. The side-lying position is more effective for both client comfort and proper placement of the suppository.

C) Left side-lying: The left side-lying position, often referred to as the Sims' position, is the most appropriate for administering a rectal suppository. This position helps to expose the rectal area, allows for easier insertion, and promotes the suppository’s absorption, as gravity can assist in its positioning within the rectum.

D) Right side-lying: The right side-lying position is not as effective as the left side-lying position for the administration of a rectal suppository. The left-side position helps to ensure the smooth placement of the suppository and promotes its absorption. Therefore, the right side is not the optimal choice.

A) Touch the tip of the bottle to the lacrimal duct: Touching the tip of the bottle to the lacrimal duct is not a recommended practice when administering eye drops. This could introduce bacteria into the eye or nose, leading to potential infection. The goal is to administer the drops without contamination, and the tip of the bottle should never touch the eye or any part of the face.

B) Apply pressure to inner canthus for 2 minutes: Applying pressure to the inner canthus (the corner of the eye near the nose) for about 2 minutes after administering ophthalmic drops is a key step when using systemically acting eye medications like propranolol. This helps to prevent the systemic absorption of the medication through the nasolacrimal duct, reducing the risk of systemic side effects such as bradycardia or hypotension. This step ensures that the medication stays localized in the eye.

C) Have client lie down or tilt the back of their head: While lying down or tilting the head back may help the client instil the drops more comfortably, it is not a required step for the proper absorption or effectiveness of eye drops. The key to effective administration lies in positioning the drop in the correct part of the eye and minimizing systemic absorption, which is achieved by applying pressure to the inner canthus, not necessarily by tilting the head.

D) Have client pull down their lower eyelid: Pulling down the lower eyelid is a standard step in administering eye drops, as it creates a small pocket to hold the drop. However, it does not specifically address the concern for reducing systemic absorption of a medication like propranolol. The primary step for preventing systemic effects is applying pressure to the inner canthus after administration, making this less relevant for this specific question.
