Nokea
A client is in ventricular tachycardia and the primary health care provider prescribes intravenous (IV) lidocaine. The nurse should dilute the concentrated solution of lidocaine with which solution?
- A. Lactated Ringer's
- B. Normal saline 0.9%
- C. 5% Dextrose in water
- D. Normal saline 0.45%
Correct Answer: C
Rationale: Lidocaine for IV administration is dispensed in concentrated and dilute formulations. The concentrated formulation must be diluted with 5% dextrose in water. Therefore, options 1, 2, and 4 are incorrect.

An infant has been found to be human immunodeficiency virus (HIV) positive. When teaching condition-specific care, which action should the nurse instruct the mother to take to minimize the child's risk for condition-related injury?
- A. Check the anterior fontanel for bulging and the sutures for widening each day.
- B. Feed the infant in an upright position with the head and chest tilted slightly back to avoid aspiration.
- C. Provide meticulous skin care to the infant and change the infant's diaper after each voiding or stool.
- D. Feed the infant with a special nipple and burp the infant frequently to decrease the tendency to swallow air.
Correct Answer: C
Rationale: Meticulous skin care helps protect the HIV-infected infant from secondary infections. Bulging fontanels, feeding the infant in an upright position, and using a special nipple are unrelated to the pathology associated with HIV.
The nurse notes an isolated premature ventricular contraction (PVC) on the cardiac monitor of a client recovering from anesthesia. Which action should the nurse take?
- A. Prepare for defibrillation.
- B. Continue to monitor the rhythm.
- C. Prepare to administer lidocaine hydrochloride.
- D. Notify the primary health care provider immediately.
Correct Answer: B
Rationale: As an isolated occurrence, the PVC is not life-threatening. In this situation, the nurse should continue to monitor the client. Frequent PVCs, however, may be precursors of more life-threatening rhythms, such as ventricular tachycardia and ventricular fibrillation. If this occurs, the primary health care provider needs to be notified. Defibrillation is done to treat ventricular fibrillation. Lidocaine hydrochloride is not needed to treat isolated PVCs; it may be used to treat frequent PVCs in a client who is symptomatic and is experiencing decreased cardiac output.
A nursing childbirth educator tells a class of expectant parents that it is standard routine to instill the ophthalmic ointment form of which medication into the eyes of a newborn infant as a preventive measure against ophthalmia neonatorum?
- A. Penicillin
- B. Neomycin
- C. Vitamin K
- D. Erythromycin
Correct Answer: D
Rationale: Ophthalmic erythromycin 0.5% ointment is a broad-spectrum antibiotic and is used prophylactically to prevent ophthalmia neonatorum, an eye infection acquired from the newborn infant's passage through the birth canal. Infection from these organisms can cause blindness or serious eye damage. Erythromycin is effective against Neisseria gonorrhoeae and Chlamydia trachomatis. Vitamin K is administered in an injectable form to the newborn infant to prevent abnormal bleeding, and it promotes liver formation of the clotting factors II, VII, IX, and X. Options 1 and 2 are incorrect and are not medications routinely used in the newborn.
The nurse notes that a large number of clients reporting the presence of flulike symptoms are being seen in the clinic. Which recommendations should the nurse provide to these clients to minimize their risk for further illness? Select all that apply.
- A. Get plenty of rest.
- B. Increase intake of liquids.
- C. Get a flu shot immediately.
- D. Take antipyretics for fever.
- E. Consume a well-balanced diet.
Correct Answer: A,B,D,E
Rationale: Treatment for the flu includes getting rest, drinking fluids, and taking in nutritious foods and beverages. Medications such as antipyretics and analgesics may also be used for symptom management. Immunizations against influenza are a prophylactic measure and are not used to treat flu symptoms.
The nurse is caring for a term newborn. Which assessment finding would predispose the newborn to the occurrence of jaundice?
- A. Presence of a cephalhematoma
- B. Infant blood type of O negative
- C. Birth weight of 8 pounds 6 ounces
- D. A negative direct Coombs' test result
Correct Answer: A
Rationale: A cephalhematoma is swelling caused by bleeding into an area between the bone and its periosteum (does not cross over the suture line). Enclosed hemorrhage, such as with cephalhematoma, predisposes the newborn to jaundice by producing an increased bilirubin load as the cephalhematoma resolves (usually within 6 weeks) and is absorbed into the circulatory system. The classic Rh incompatibility situation involves an Rh-negative mother with an Rh-positive fetus/newborn. The birth weight in option 3 is within the acceptable range for a term newborn and therefore does not contribute to an increased bilirubin level. A negative direct Coombs' test result indicates that there are no maternal antibodies on fetal erythrocytes.
