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 is caring for a client diagnosed with active tuberculosis who is prescribed rifampin therapy. The nurse instructs the client to expect which side effect of this medication?
- A. Green urine
- B. Yellow sclera
- C. Orange secretions
- D. Clay-colored stools
Correct Answer: C
Rationale: Rifampin is an antituberculosis medication. Secretions will become orange in color as a result of the rifampin. The client should be instructed that this side effect will likely occur.
A client has an arteriovenous (AV) fistula in place in the right upper extremity for hemodialysis treatments. When planning care for this client, which measure should the nurse implement to promote client safety?
- A. Use the right arm blood pressure measurement.
- B. Use the fistula for all venipunctures and intravenous infusions.
- C. Ensure that small clamps are attached to the AV fistula dressing.
- D. Assess the fistula for the presence of a bruit and thrill every 4 hours.
Correct Answer: D
Rationale: AV fistulas are created by anastomosis of an artery and a vein within the subcutaneous tissues to create access for hemodialysis. Fistulas should be evaluated for presence of thrills (palpate over the area) and bruits (auscultate with a stethoscope) as an assessment of patency. Blood pressures or venipunctures are not done on the extremity with the fistula because of the risk of clotting, infection, or damage to the fistula. The fistula is not used for venipunctures or intravenous infusions for the same reason. Clamps may be needed for an external device such as an AV shunt, but the AV fistula is internal.
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 is caring for a client scheduled to undergo a cardiac catheterization for the first time. Which information should the nurse share with the client regarding the procedure?
- A. The procedure is performed in the operating room.
- B. The initial catheter insertion is quite painful; after that, there is little or no pain.
- C. You may feel fatigue and have various aches because it is necessary to lie quietly on a stationary x-ray table for about 4 hours.
- D. You may feel certain sensations at various points during the procedure, such as a fluttery feeling, flushed warm feeling, desire to cough, or palpitations.
Correct Answer: D
Rationale: Cardiac catheterization is an invasive test that involves the insertion of a catheter and the injection of dye into the heart and surrounding vessels to obtain information about the structure and function of the heart chambers and valves and the coronary circulation. Access is made by the insertion of a needle in either side of the groin into an artery and the catheter is advanced up to the heart through the abdomen and chest. Preprocedure teaching points include that the procedure is done in a darkened cardiac catheterization room and that ECG leads are attached to the client. A local anesthetic is used so that there is little to no pain with catheter insertion. The x-ray table is hard but can be tilted periodically. The procedure may take up to 2 hours, and the client may feel various sensations with catheter passage and dye injection.
