A nurse is assessing a client who has received oxycodone. The nurse notes that the client's respiratory rate is 8/min. The nurse should identify that which of the following is the pathophysiology for the client's respiratory rate?

A) Ex edicationr bubble from the syringe prior to administering the medication: Expelling air bubbles is necessary when administering medications via intravenous injection to prevent air embolisms. However, with subcutaneous injections like enoxaparin, the presence of small air bubbles is not usually a concern, and expelling them is not necessary.

B) Administer the medication into the anterolateral or posterolateral abdominal area: This is the correct action for administering enoxaparin. Enoxaparin is typically administered subcutaneously into the anterolateral or posterolateral abdominal wall. This site is preferred due to its high vascularity and good absorption of the medication.

C) Hold the skin taut at the injection site while administering the medication: While holding the skin taut can help reduce discomfort during the injection, it is not always necessary. The choice to hold the skin taut depends on the client's body habitus and the nurse's preferenc’. It is not a specific requi’ement for administering enoxaparin.

D) Massage the injection site after administering the medication: Massaging the injection site after administering enoxaparin is not recommended. It can increase bruising or bleeding at the injection site. Instead, after administering the medication, the nurse should apply gentle pressure with a dry cotton ball or gauze pad to help minimize bleeding.

A) Hematuria: Hematuria, or blood in the urine, is not typically associated with an allergic reaction to cefaclor. Allergic reactions usually manifest with symptoms such as rash, itching, swelling, or difficulty breathing. Hematuria is more likely indicative of a urinary tract infection, kidney stones, or another non-allergic issue.

B) Pruritus: Pruritus, or itching, is a common symptom of an allergic reaction to medications like cefaclor. Itching can occur on the skin or mucous membranes and may be accompanied by other allergic symptoms such as rash, hives, or swelling. Therefore, the presence of pruritus should raise suspicion for a potential allergic reaction to cefaclor.

C) Slurred speech: Slurred speech is not a typical manifestation of an allergic reaction to cefaclor. It is more commonly associated with neurological conditions, intoxication, stroke, or side effects of certain medications, rather than an allergic response to antibiotics.

D) Tremor: Tremor, or involuntary shaking, is not a characteristic sign of an allergic reaction to cefaclor. Tremors can have various causes, including neurological disorders, medication side effects, or metabolic abnormalities. While tremors can occur in severe allergic reactions (anaphylaxis), they are not among the primary symptoms.
