B)Assist the parents to plan quiet play activities at home
C)Stress to the parents that they will need relief care givers
D)Instruct the parents to avoid contact with persons with infection 

The correct answer is A: Encourage the parents to enroll in cardiopulmonary resuscitation class
While all suggestions are appropriate, the education of the parents/caregivers should include techniques of cardiopulmonary resuscitation in order to provide for emergency care of their child.

2.      The nurse notes an abrupt onset of confusion in an elderly patient. Which of the following recently-ordered medications would most likely contribute to this change?
A)               Anticoagulant
B)                 Liquid antacid
C)               Antihistamine
D)               Cardiac glycoside
The correct answer is C: Antihistamine
Elderly people are susceptible to the side effect of anticholinergic drugs, such as antihistamines. Especially at high doses, antihistamines often cause confusion in the elderly.

3.      An infant has just returned from surgery for placement of a gastrostomy tube as an initial treatment for tracheoesophageal fistula. The mother asks:”When can the tube can be used for feeding?” The nurse's best response would be which of these comments?
A)               Feedings can begin in 5 to 7 days.
B)                 The use of the feeding tube can begin immediately.
C)               The stomach contents and air must be drained first.
D)               The incision healing must be complete before feeding.

The correct answer is C: Stomach contents and air must be drained first
After surgery for gastrostomy tube placement, the catheter is left open and attached to gravity drainage for 24 hours or more

4.      The nurse is teaching a 27 year-old client with asthma about management of their therapeutic regime. Which statement would indicate the need for additional instruction?
A)               "I should monitor my peak flow every day."

D)               "I should learn stress reduction and relaxation techniques."

The correct answer is C: "I need to limit my exercise, especially activities such as walking and running."
Limiting physical activity in an otherwise healthy, young client should not be necessary. If exercise intolerance exists, the asthma management plan should include specific medications to treat the problem such as using an inhaled beta-agonist 5 minutes before exercise. The goal is always to return to a normal lifestyle.

5.      A nurse caring for premature newborns in an intensive care setting carefully monitors oxygen concentration. What is the most common complication of this therapy?
A)               Intraventricular hemorrhage
B)                 Retinopathy of prematurity
C)               Bronchial pulmonary dysplasia
D)               Necrotizing enterocolitis

The correct answer is B: Retinopathy of prematurity
While there are other causes for retinal damage in the premature infant, maintaining the oxygen concentration below 40% reduces one risk factor

6.      The nurse is caring for a child with cystic fibrosis. The nurse would anticipate that the child would be deficient in which vitamins?

A)               Large indoor gatherings
B)                 Exposure to sunlight
C)               Active physical exercise
D)               Foods rich in vitamin K
The correct answer is D: Foods rich in vitamin K
Vitamin K acts as an antidote to the pharmacologic action of Coumadin therapy, decreasing Coumadin''s effectiveness. Foods high in vitamin K include dark greens, tomatoes, bananas, cheese, and fish

9.      To prevent keratitis in an unconscious client, the nurse should apply moisturizing ointment to the:
A)               Finger and toenail quicks
B)                 Eyes
C)               Perianal area

A)               "I can only wear cotton socks."
B)                 "I cannot go barefoot around my house."
C)               "I will trim corns and calluses regularly."
D)               "I should ask a family member to inspect my feet daily."

The correct answer is C: "I will trim corns and calluses regularly."
Clients who are elderly, have diabetes, and/or have vascular disease often have decreased circulation and sensation in one or both feet. Their vision may also be impaired. Therefore, they need to be taught to examine their feet daily or have someone else do so. They should wear cotton socks which have not been mended, and always wear shoes when out of bed. They should not cut their nails, corns, and calluses, but should have them trimmed by their health care provider, nurse, or other provider who specializes in foot care.

A)               Cardiopulmonary resuscitation
B)                 Insertion of a chest tube
C)               Oxygen therapy
D)               Assisted ventilation
Your response was "A". The correct answer is B: Insertion of a chest tube Because a portion of the lung has collapsed, a chest tube will be inserted to restore negative pressure in the chest cavity.

15. The nurse is teaching a group of adults about modifiable cardiac risk factors. Which of the following should the nurse focus on first?
A)               Weight reduction
B)                 Stress management
C)               Physical exercise

A)               Kicking balloons with right leg
B)                 Playing "Simon Says"
C)               Playing hand held games
D)               Throw bean bags
The correct answer is C: Playing hand held games
Immobilization with traction must be maintained until bone ends are in satisfactory alignment. Activities that increase mobility interfere with the goals of treatment.

Blood lipid levels should be measured on a fasting sample

18. Which of these clients would the triage nurse request for the health care provider to examine immediately?
A)               A 5 month-old infant who has audible wheezing and grunting
B)                 An adolescent who has soot over the face and shirt
C)               A middle-aged man with second degree burns over the right hand
D)               A toddler with singed ends of long hair that extends to the waist
The correct answer is A: A 5 month-old infant who has audible wheezing and grunting
The age and the findings puts this client at immediate risk for respiratory complications.

19. In assessing a post partum client, the nurse palpates a firm fundus and observes a constant trickle of bright red blood from the vagina. What is the most likely cause of these findings?
A)               Uterine atony
B)                 Genital lacerations
C)               Retained placenta
D)               Clotting disorder

The correct answer is B: Genital lacerations
Continuous bleeding in the absence of a boggy fundus indicates undetected genital tract lacerations.

20. The community health nurse has been following the care for an adolescent with a history of morbid obesity, asthma, hypertension and is 22 weeks in to a pregnancy. Which of these lab reports sent to the clinic need to be called to the teens health care provider within the next hour?
A)               Hemoblobin 11 g/L and calcium 6 mg/dl
B)                 Magnesium 0.8 mEq/L and creatinine 3 mg/dl
C)               Blood urea nitrogen 28 and glucose 225 mg/dl
D)               Hematocrit 33% and platelets 200,000

The correct answer is B: Magnesium 0.8 mEq/L and creatinine 3 mg/dl
The client’s lab values are all abnormal except for the platelets. The magnesium is low and the creatinine is high which indicates renal failure. With the history of hypertension the findings exhibit the risk of preeclampsia. The client needs to be referred for immediate follow up with a health care provider.
