Which is the proper hand position for performing chest percussion?

Correct Answer: D

Rationale: The proper hand position for performing chest percussion is to cup the hands. Cupping the hands helps produce a vibration that aids in loosening respiratory secretions effectively. This technique is essential for therapeutic chest physiotherapy. Using the side of the hands, flattening the hands, or spreading the fingers of both hands do not generate the necessary vibration required for chest percussion. These hand positions are not considered proper techniques in this context and may not provide the desired therapeutic effect.

Correct Answer: A

Rationale: The correct answer is 'when there is presence of blood and body fluids.' When handling body substances like blood and body fluids, the risk of transmission of infections increases. Federal regulations mandate warning labels on containers to alert employees and waste collectors. The biohazard emblem consists of a three-ring symbol overlaying a central concentric ring. Blood, wound drainage, feces, and urine are examples of body fluids that can transmit infections and diseases to others. The other choices, B, C, and D, are incorrect because the presence of the biohazard emblem is specifically linked to the handling of blood and body fluids, not to droplet precautions, contact isolation, or airborne transmission.

Correct Answer: B

Rationale: A client with hypercholesterolemia should decrease their intake of foods high in cholesterol. Hamburgers, being red meat, have a high cholesterol content, hence should be decreased in the diet. Broiled catfish, wheat bread, and fresh apples are not high in cholesterol, so there is no need to decrease their intake. Broiled catfish is a lean source of protein, wheat bread is a complex carbohydrate, and fresh apples are a good source of fiber and vitamins. Therefore, hamburgers are the correct choice to decrease intake for a client with hypercholesterolemia.

Correct Answer: A

Rationale: Variable decelerations can indicate cord compression as they are caused by umbilical cord compression or prolapse. This pattern shows an abrupt decrease in heart rate with an erratic shape, often resembling a V or W. Early decelerations (choice B) are typically caused by head compression during contractions and are considered benign. Bradycardia (choice C) is a consistent low heart rate below 110 bpm and is not specific to cord compression. Tachycardia (choice D) is an abnormally high heart rate above 160 bpm and is not associated with cord compression.

Correct Answer: C

Rationale: Carrying a donor card for organ donation signifies that an individual can decide to revoke their decision for organ donation at any point. This choice empowers the individual to change their mind regarding organ donation. The family or legally responsible party of a client still holds decision-making authority in the event that the client is considered for organ donation. When organ donation is being considered, all organs or tissues the donor wishes to donate are evaluated for donation suitability; it's not limited to just one organ or tissue. It's important to note that medical care for an individual is not altered to hasten the declaration of death for organ donation purposes; the focus is on providing immediate care and resuscitation to the individual.
