- A. Lactated Ringer's
- B. Normal saline 0.9%
- C. 5% Dextrose in water
- D. Normal saline 0.45%

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.
A client diagnosed with renal cancer is being treated preoperatively with radiation therapy. The nurse evaluates that the client has an understanding of proper care of the skin over the treatment field when the client makes which statement?
- A. I'll be able to wash the ink marks off my skin after the initial treatment.
- B. Direct sunlight is something I'll have to really avoid exposing my skin to.
- C. I'll have my family bring me some unscented lotion to keep my skin soft.
- D. Wearing snug fitting clothing over the skin site will help provide good support.
Correct Answer: B
Rationale: The client undergoing radiation therapy must keep the affected skin protected from temperature extremes, direct sunlight, and chlorinated water (as from swimming pools). The client should wash the site using mild soap and warm or cool water and pat the area dry. Lines or ink marks that are placed on the skin to guide the radiation therapy should be left in place. No lotions, creams, alcohol, perfumes, or deodorants should be placed on the skin over the treatment site. The client should wear cotton clothing over the skin site and guard against irritation from tight or rough clothing such as belts or bras.
The nurse is developing a care plan for a client experiencing urge urinary incontinence. Which interventions would be helpful for this type of incontinence? Select all that apply.
- A. Surgery
- B. Bladder retraining
- C. Scheduled toileting
- D. Dietary modifications
- E. Pelvic muscle exercises
- F. Intermittent catheterization
Correct Answer: B,C,D,E
Rationale: Urge incontinence is the involuntary passage of urine after a strong sense of the urgency to void. It is characterized by urinary urgency, often with frequency (more often than every 2 hours); bladder spasm or contraction; and voiding in either small amounts (less than 100 mL) or large amounts (greater than 500 mL). It can be caused by decreased bladder capacity, irritation of the bladder stretch receptors, infection, and alcohol or caffeine ingestion. Interventions to assist the client with urge incontinence include bladder retraining, scheduled toileting, dietary modifications such as eliminating alcohol and caffeine intake, and pelvic muscle exercises to strengthen the muscles. Surgery and urinary catheterization are invasive measures and will not assist in the treatment of urge incontinence.
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.
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.
