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: 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: C

Rationale: The correct action when removing a client's gown with an intravenous line is to thread the bag and tubing through the gown sleeve while keeping the line intact. This method ensures that the system remains sterile and reduces the risk of infection. Temporarily disconnecting the tubing at a point close to the client or from the container introduces the potential for contamination. Cutting the gown with scissors should only be done in emergencies as it is not a standard practice and can compromise the integrity of the intravenous line. Therefore, the most appropriate and safe method is to thread the bag and tubing through the gown sleeve.

Correct Answer: B

Rationale: The correct answer is B: '4'. The FLACC pain scale assesses pain in non-verbal patients based on five categories: Face, Legs, Activity, Cry, and Consolability. In this case, the client exhibits occasional grimacing (1 point), relaxed legs (0 points), squirming (1 point), moans and whimpers (1 point), and is distractible (1 point). Adding these points together results in a total pain score of 4. Therefore, the LPN should document a pain score of 4 for this non-verbal client. Choices A, C, and D are incorrect as they do not accurately reflect the total pain score based on the given findings.

Correct Answer: B

Rationale: The correct answer is that the disorder is uncommon in adults. Erythema infectiosum, also known as Fifth's disease, commonly affects children and is characterized by a 'slapped face' appearance. It is associated with a rash and sometimes a low-grade fever. Therefore, the statement 'The disorder is uncommon in adults' is not correct, making it the correct answer. The other statements about the presence of a rash, 'slapped face' appearance, and the possibility of a fever are accurate in the context of erythema infectiosum.
