1. The key to the prevention of a pandemic influenza is:

A. Early detection
B. Early antibiotic treatment
C. Vaccination of at-risk populations
D. Isolation of suspected cases

Correct answer: A

Rationale: The key to preventing a pandemic influenza is early detection. Detecting influenza cases early allows for timely public health responses to limit the spread of the virus. Early detection helps in implementing measures such as isolation, treatment, and vaccination to prevent the development of a full-blown pandemic. Antibiotics are not effective against influenza viruses, so early antibiotic treatment is not the key to prevention. While vaccination of at-risk populations is important in controlling the spread of influenza, early detection is crucial as it allows for timely implementation of vaccination strategies. Isolation of suspected cases is a containment measure rather than a prevention strategy; the key to prevention lies in early detection to stop the spread before it becomes a pandemic.

2. A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but the diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability.

A. A lumbar puncture takes a sample of cerebrospinal fluid from the back, which will be analyzed by the lab.
B. The physician will insert a needle at the level of L4-L5 in the spinal cord.
C. The client should lie flat on their back for a specific period following the procedure.
D. The risks of the procedure include headache, back pain, and infection.

Correct answer: B

Rationale: A lumbar puncture is performed to obtain cerebrospinal fluid for analysis to investigate various conditions affecting the client. During the procedure, the client is typically positioned on their side or sitting leaning over a table with their back rounded. The physician inserts a needle into the back around the L4-L5 vertebrae to collect the sample. Option A is incorrect because a lumbar puncture does not draw blood but instead collects cerebrospinal fluid. Option C is incorrect as the client should not necessarily lie flat for 24 hours post-procedure. Option D is incorrect as the common risks of a lumbar puncture include headache, back pain, and potential infection, not nausea, rash, or hypotension.

3. Richard is a 72-year-old with stage 4 lung cancer who has been admitted to the hospital for pneumonia. He is alert and oriented and states he would like to sign a do not resuscitate (DNR) order. His wife enters the room after he has signed it and is very upset that he has made this decision without discussing it with her. She wants to know what she can do to get the DNR reversed. What should your first response be?

A. Contact the unit manager to talk with her
B. Contact the hospital's attorney to discuss with her
C. Try to talk Richard out of his decision
D. Offer caring support for both parties

Correct answer: D

Rationale: The correct response in this situation is to offer caring support for both parties. Richard, being alert and oriented, has the right to make his own decisions, including signing a do not resuscitate (DNR) order. It is important to respect his autonomy while also acknowledging his wife's feelings. By offering caring support, the nurse can facilitate a discussion between Richard and his wife, helping them navigate their emotions and decisions. Contacting the unit manager or hospital's attorney would not be appropriate as the initial response. These actions may escalate the situation and are not focused on addressing the emotional needs of the couple. Trying to talk Richard out of his decision would disregard his autonomy and right to make choices about his own care, which goes against ethical principles of patient autonomy and informed decision-making.

4. Which of the following tasks may be delegated to unlicensed assistive personnel?

A. Cleansing a wound with peroxide
B. Irrigating a colostomy
C. Assisting with performing incentive spirometry
D. Removing a saline-lock IV

Correct answer: C

Rationale: Certain tasks can be safely delegated to unlicensed assistive personnel to assist nurses in their workload. Tasks that involve routine activities like incentive spirometry can be delegated. Unlicensed assistive personnel can assist clients with incentive spirometry, helping in promoting lung expansion and preventing respiratory complications. Cleansing a wound with peroxide (Choice A) and irrigating a colostomy (Choice B) involve more complex procedures that should be performed by licensed healthcare providers due to the risk of infection and potential complications. Removing a saline-lock IV (Choice D) requires specialized training and should only be performed by licensed personnel to prevent complications and ensure patient safety. The nurse remains responsible for delegating tasks appropriately and overseeing the care provided by unlicensed assistive personnel.

5. A nurse is caring for a 3-day old infant who needs an exchange transfusion. Which of the following statements is appropriate for teaching the child's parents about this procedure?

A. The registered nurse will be performing the procedure
B. The procedure takes approximately 1 ? hours.
C. The nurse will draw out 250cc of blood and then immediately replace it with 250cc
D. The infant will continue to receive phototherapy during the procedure.

Correct answer: B

Rationale: : An exchange transfusion is a method of controlling high bilirubin levels in infants when traditional phototherapy is unsuccessful. During an exchange transfusion, the physician removes 5-10 cc of blood and then replaces it with donor blood. The parents of this infant should know that the procedure is always performed by a physician and will take approximately 1 � hours to complete.
