1. What effect can medication bound to protein have?

• A. reduced drug availability
• B. limited distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. decreased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.

2. A nurse calculates a newborn infant's Apgar score 1 minute after birth and determines that the score is 6. What is the most appropriate action for the nurse to take?

• A. Initiate cardiopulmonary resuscitation
• B. Gently stimulate the infant by rubbing his back while administering oxygen
• C. Recheck the score in 5 minutes
• D. Provide no action except to support the infant's spontaneous efforts

Correct answer: B

Rationale: The Apgar score is a method for rapidly evaluating an infant's cardiorespiratory adaptation after birth. The nurse assigns scores in five areas: heart rate, respiratory effort, muscle tone, reflex response, and color, totaling the scores. A score of 8 to 10 requires no action other than supporting the infant's spontaneous efforts and observation. A score of 4 to 7 indicates the need to gently stimulate the infant by rubbing his back while administering oxygen. If the score is 1 to 3, the infant requires resuscitation. Therefore, in this scenario with an Apgar score of 6, the correct action is to gently stimulate the infant by rubbing his back while administering oxygen. Initiating cardiopulmonary resuscitation would be excessive at this point, and rechecking the score in 5 minutes may delay necessary interventions. Providing no action except to support the infant's spontaneous efforts is insufficient for a score of 6, indicating the need for stimulation and oxygen administration.

3. The LPN needs to determine the client's respiratory rate. What is the best technique to do this?

• A. Tell the client you need to count their respiratory rate.
• B. Subtly watch the client from across the room when they are doing an activity.
• C. Ask the client to sit still for 30 seconds.
• D. Count respirations while pretending to check the client's pulse.

Correct answer: D

Rationale: The best technique to determine a client's respiratory rate is to count respirations while pretending to check the client's pulse. You should not inform the client that you are counting their respirations, as this might lead to a change in their breathing pattern. Pretending to check the pulse allows you to be close to the client without revealing that you are assessing their respiratory rate. Asking the client to sit still may not be as effective, as it may cause them to concentrate on their breathing. Watching from across the room may not provide an accurate assessment of respirations, as they might be difficult to observe.

4. A nurse sees documentation in the client's record indicating that the health care provider has noted the presence of adventitious breath sounds. The nurse knows that these types of sounds have which aspect?

• A. Normally heard in the lungs
• B. Hollow sounds heard over the trachea and larynx
• C. Rustling sounds heard over the peripheral lung fields
• D. Abnormal sounds that should not be heard in the lungs

Correct answer: D

Rationale: Adventitious breath sounds are abnormal sounds that are not normally heard in the lungs. These sounds are added sounds superimposed on the breath sounds. They are caused by air colliding with secretions in the tracheobronchial passageways or when previously deflated airways pop open. Hollow sounds heard over the trachea and larynx are normal bronchial (tracheal) breath sounds, not adventitious. Rustling sounds heard over the peripheral lung fields are normal vesicular breath sounds, not adventitious. Therefore, the correct answer is that adventitious breath sounds are abnormal sounds that should not be heard in the lungs.

5. A nurse preparing to assist with data collection of the abdomen asks the client to void and then assists the client into a supine position. Which primary finding does the nurse expect to note on percussing all four quadrants of the abdominal cavity?

• A. Dullness
• B. Tympany
• C. Borborygmus
• D. Hyperresonance

Correct answer: B

Rationale: The nurse expects to primarily note tympany when percussing the abdomen. Tympany should predominate because air in the intestines rises to the surface when the client is in a supine position. Dullness is usually heard over a distended bladder, adipose tissue, fluid, or a mass. Borborygmus, which refers to hyperperistalsis, is typically heard on auscultation, not percussion. Hyperresonance is present with gaseous distention, not the typical finding when percussing all four quadrants of the abdomen.
