What is the function of the epiglottis during swallowing?
- A. Prevents food from entering the trachea
- B. Aids in food propulsion
- C. Enhances taste sensation
- D. Lubricates the esophagus
Correct Answer: A
Rationale: The epiglottis is a flap of tissue that closes over the trachea during swallowing to prevent food and liquids from entering the airway. Choice A is correct because the primary function of the epiglottis is to act as a lid over the trachea, ensuring that food goes down the esophagus and not into the windpipe. Choices B, C, and D are incorrect as they do not describe the specific role of the epiglottis during swallowing.

The home health PN suspects elder abuse after observing fresh lacerations on the arms and legs of an older adult male client who lives with his daughter. Which action is most important for the PN to take?
- A. Document the lacerations in the client's record
- B. Report findings to the supervisor for referral to adult protective services
- C. Ask the daughter who has been taking care of the client on a daily basis
- D. Apply dry dressings after cleansing the wounds
Correct Answer: B
Rationale: The most important action for the PN to take in this situation is to report the findings to the supervisor for referral to adult protective services. Suspected elder abuse must be reported promptly to ensure the safety and protection of the client. Documenting the lacerations in the client's record is important but not as critical as reporting the suspected abuse. Asking the daughter who is the potential abuser may not yield accurate information and could compromise the safety of the client. Applying dressings to the wounds is a lower priority compared to addressing the suspected elder abuse.
What is the primary role of the sinoatrial (SA) node in the heart?
- A. Pacemaker of the heart
- B. Blood pressure regulation
- C. Electrical conduction delay
- D. Stimulating muscle contraction
Correct Answer: A
Rationale: The correct answer is A: Pacemaker of the heart. The SA node, known as the natural pacemaker, initiates the electrical impulses that set the rhythm for the heartbeat. It is responsible for coordinating the heart's contractions by generating electrical signals at regular intervals. Choice B is incorrect as the SA node's primary function is not related to blood pressure regulation. Choice C is incorrect as the SA node does not cause electrical conduction delay but rather initiates and conducts the electrical impulses. Choice D is incorrect as the SA node does not directly stimulate muscle contraction but rather initiates the electrical events that lead to muscle contraction.
Which action should the PN implement when using standard precautions to provide client care?
- A. Apply sterile gloves to obtain a finger stick blood sample
- B. Wear clean exam gloves to perform perineal catheter care
- C. Replace the needle cap after giving an intramuscular injection
- D. Wear a paper gown to prevent transmission of droplet pathogens
Correct Answer: B
Rationale: The correct answer is B. When using standard precautions, healthcare providers should wear clean exam gloves to perform perineal catheter care. This approach helps prevent the transmission of pathogens and ensures the safety of both the client and the healthcare provider. Choice A is incorrect because applying sterile gloves for a finger stick blood sample is unnecessary when non-sterile gloves would suffice. Choice C is incorrect because replacing the needle cap after giving an intramuscular injection is not directly related to standard precautions. Choice D is incorrect because wearing a paper gown is not a standard precaution for preventing the transmission of droplet pathogens.
The UAP is caring for a male resident of a long-term care facility who has an external urinary catheter. Which finding should the PN instruct the UAP to report immediately?
- A. Swollen and discolored penile shaft
- B. Prepuce extends over the head of the penis
- C. Leaking urine around the top of the catheter
- D. Moist and excoriated perineal skin folds
Correct Answer: A
Rationale: The correct answer is A: Swollen and discolored penile shaft. Swelling and discoloration of the penile shaft may indicate an infection or other complications requiring immediate attention. Prompt reporting allows for timely intervention to prevent further harm to the client. Choice B is incorrect because the prepuce extending over the head of the penis is not an urgent issue. Choice C, leaking urine around the catheter, may require intervention but is not as urgent as the swelling and discoloration described in choice A. Choice D, moist and excoriated perineal skin folds, also needs attention but is not as concerning as the potential complications indicated by the findings in choice A.
Which intervention is most appropriate when caring for a patient experiencing a tonic-clonic seizure?
- A. Restrain the patient to prevent injury
- B. Place a tongue depressor in the patient's mouth
- C. Turn the patient to the side to maintain an open airway
- D. Attempt to stop the seizure by holding the patient's arms
Correct Answer: C
Rationale: During a tonic-clonic seizure, the priority is to ensure patient safety by maintaining an open airway to prevent aspiration. Turning the patient to the side helps achieve this goal by allowing any fluids to drain out of the mouth, reducing the risk of choking or aspiration. Restraint can lead to injury, placing a tongue depressor can cause harm or obstruct the airway further, and attempting to stop the seizure by holding the patient's arms is ineffective and can also result in injury. Therefore, the most appropriate intervention is to turn the patient to the side.
