A client currently prescribed a medication highly metabolized by the CYP 450 recently began smoking due to a stressful life event. True or False: The level of medication will increase in this client.

A) 90 degrees: For intramuscular (IM) injections, including in the ventrogluteal site, the needle should be inserted at a 90-degree angle to ensure that the medication is deposited deep into the muscle tissue. This angle allows the needle to penetrate the skin and subcutaneous tissue directly into the muscle where it can be absorbed efficiently. The ventrogluteal site, being a large and well-muscled area, is ideal for IM injections because it is less likely to cause damage to nerves or blood vessels, and a 90-degree angle ensures proper placement of the medication.

B) 45 degrees: A 45-degree angle is commonly used for subcutaneous injections which go into the fatty tissue just beneath the skin. This angle ensures that the medication is delivered into the correct layer of tissue, allowing for slow absorption. However, when administering an IM injection, a 45-degree angle would not be deep enough to reach the muscle and could result in improper placement, potentially affecting the medication's effectiveness and increasing the risk of irritation at the injection site.

C) 15 degrees: A 15-degree angle is far too shallow for an intramuscular injection and is typically used for intradermal injections, where the medication is injected just beneath the skin into the dermal layer. Using such a shallow angle for an IM injection would likely cause the needle to remain in the subcutaneous tissue, preventing the medication from reaching the muscle layer and significantly reducing its effectiveness.

D) 60 degrees: A 60-degree angle is too steep for intramuscular injections. At this angle, the needle may not effectively reach the muscle tissue and could cause the medication to be injected too superficially into the subcutaneous layer. This would not allow for proper absorption of the drug and may lead to irritation or a delayed therapeutic effect.

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.
