o Azithromycin is well tolerated and does not commonly result in intense nausea. The most common reactions are diarrhea (5%) and nausea and abdominal pain (3%). o Combining a beta-lactamase inhibitor with a penicillinase-sensitive penicillin can extend the spectrum of the penicillin. Extending the spectrum will enable it to cover only those bacteria that have developed beta-lactamase. It will not be broader than its original intent. o Age-related physiological factors and anesthetic changes increase the risk for hypothermia in older adult patients undergoing surgery. o The nurse should flush the intravenous lock with normal saline by pushing the plunger slowly to clear the lock of blood. Flushing the lock with normal saline does not prevent the transmission of infection nor control the infusion rate of the bolus. The nurse should pull back gently on the syringe plunger and look for blood return to determine whether the needle is properly positioned in the vein. o When the nurse is caring for the patient at home, the priority action is to assess the adequacy of light. Sufficient lighting in the room ensures that everything is visible and
reduces the risk for injuries. The presence of safety devices, the presence of locks, and the kitchen and bathroom should be assessed after the adequacy of light is assessed. o After verifying the insulin dosages with the medication administration record (MAR) a third time, the nurse should show the insulin prepared in the syringe to another nurse to verify that the correct dosage is prepared. This is considered part of the third accuracy check. The nurse should review the patient’s medical history and any allergies to various medications; this is unrelated to the third accuracy check. While mixing the two types of insulin in one syringe, the first step is to check the accuracy and completeness of each MAR ordered by the primary health care provider. The nurse should verify the insulin dosages against the medication administration (MAR) before wiping the insulin vials tops with alcohol as part of the second accuracy check. o Human papillomavirus causes cervical cancer in women and anogenital cancers and warts in both men and women. Chlamydia trachomatis infection does not cause malignancies but can cause urinary and pelvic symptoms. Neisseria gonorrhoeae infection causes urethritis and does not lead to any malignancy. Herpes simplex causes recurrent genital lesions. o The first step for administering nasal drops is to place the patient in the supine position and place the head properly. The second step is to support the patient’s head with the nondominant hand. The third step is to hold the dropper 1 cm (12 inches) above the nares. The fourth step is instillation of the prescribed number of drops toward the midline of the ethmoid bone. The fifth step is to instruct the patient to remain in the supine position for 5minutes so that the medication is properly delivered to the site. The sixth step is to offer facial tissues to the patient to blot a runny nose.
