Why would a Heimlich maneuver be performed on a client?
- A. To increase the absorption of the prescribed medication
- B. To clear the airway if the client cannot speak or breathe after swallowing food
- C. To reduce the potential for injuries as a result of falls
- D. To maintain extremities in proper anatomic position CARING FOR CLIENT WITH HEAD AND SPINAL CORD TRAUMA
Correct Answer: B
Rationale: The Heimlich maneuver, also known as abdominal thrusts, is performed on a client to clear the airway if the client is choking and cannot speak or breathe after swallowing food. The maneuver involves applying upward pressure on the abdomen in an effort to forcefully expel the object blocking the airway. It is a crucial life-saving technique that can prevent the client from suffocating due to an obstructed airway. In cases of choking emergencies, the Heimlich maneuver should be administered promptly to effectively remove the obstruction and restore breathing.
A neonate has been diagnosed with caput succedaneum. Which statement is correct about this condition?
- A. It usually resolves in 3-6 weeks
- B. It doesn't cross the cranial suture line
- C. It's a collection of blood between the skull and the periosteum
- D. It involves swelling of tissue over the presenting part of the presenting head
Correct Answer: D
Rationale: Caput succedaneum is a condition characterized by the swelling of tissue over the presenting part of the infant's head during delivery. It is commonly a result of prolonged labor or vacuum extraction. Unlike cephalohematoma, caput succedaneum does cross the cranial suture lines. This condition typically resolves within a few days to a week after birth without intervention. It is important to monitor the infant for any complications or signs of infection during the resolution process.
The most common buffer system in the body is the:
- A. Plasma protein buffer system
- B. Phosphate buffer system
- C. Hemoglobin buffer system
- D. Bicarbonate-carbonic system
Correct Answer: D
Rationale: The most common buffer system in the body is the bicarbonate-carbonic system. This system plays a crucial role in maintaining the pH balance in the blood. The bicarbonate ion (HCO3-) acts as a weak base, while carbonic acid (H2CO3) acts as a weak acid. The balance between these two components helps to regulate the pH of the blood.
