NCLEX-RN safety and infection control practice questions set 4

Correct answer:

The correct answer is D, 'ABC.' The ABC method stands for Airway, Breathing, Circulation. When encountering an unconscious patient, it is crucial to first ensure their Airway is clear by performing the 'head tilt, chin lift' maneuver. Next, assess Breathing by observing for chest rise and fall, listening for breath sounds, and feeling for airflow. Finally, check for Circulation by assessing for a pulse. Choices A, B, and C ('WBC,' 'QRS,' 'XYZ') are incorrect as they do not represent the standard approach to assessing an unconscious patient.

Correct answer:

The correct answer is 'Hands of healthcare workers.' MRSA is primarily transmitted via the unwashed hands of healthcare workers who can carry the Staphylococcus aureus bacterium from one patient to another. Shared needles, items in the healthcare environment, and blood transfusions are not the main routes of transmission for MRSA. Shared needles can transmit bloodborne pathogens, items in the healthcare environment can harbor bacteria but are not the primary mode for MRSA, and blood transfusions are not a common route for MRSA transmission.

Correct answer:

The correct answer is gloves. When attending a high-risk delivery and handling a newborn immediately after birth, the minimum personal protective equipment required for a nurse includes gloves. This is essential to protect the nurse from potential exposure to the mother's blood or body fluids that may be present on the newborn's skin. Choices A, B, and D include additional protective equipment that is not necessary for this specific scenario. Wearing gloves is crucial for infection control and to prevent the transmission of pathogens.

Correct answer:

The most appropriate first aid procedure for a patient bleeding profusely from an injury near the wrist is to place pressure on her brachial artery. Applying pressure to the brachial pulse point will help slow down the bleeding. Placing a tourniquet on her arm above the injury is not recommended as it could potentially inhibit blood flow, leading to tissue necrosis. Pressing on the radial nerve or covering the bleeding area with wet towels are not effective in controlling bleeding and may not address the underlying cause.

Correct answer:

Stridor is the sound produced by turbulent airflow through a partially obstructed upper airway. It is a classic sign of upper airway obstruction. While an elongated expiratory phase may indicate lower airway obstruction, stridor specifically points to an upper airway issue. Retractions are also often seen in upper airway obstruction due to the increased effort of breathing. Expiratory wheezing, on the other hand, is more indicative of lower airway conditions such as asthma or chronic obstructive pulmonary disease (COPD).

Correct answer:

A client undergoing high-dose brachytherapy has a radiation implant placed for cancer treatment. To ensure safety, the client should be in a private hospital room to prevent radiation exposure to others. Limiting visits from friends and family is necessary to prevent overexposure. Option A is incorrect as isolation under airborne precautions is not required for brachytherapy. Option B and C are the correct choices as they focus on minimizing radiation exposure to others, ensuring safety during treatment.

Correct answer:

The primary purpose of emergency planning is to ensure and maintain the safety of people and the preservation of objects, such as buildings and personal possessions during emergencies or disasters. While compliance with state and federal laws regarding emergency planning is important, the main goal is to prioritize life and safety. Choices A, B, and C focus on legal compliance, which is necessary but secondary to the fundamental objective of safeguarding lives and property in emergency situations.

Correct answer:

High-quality CPR for adults should not be paused for drug administration. The correct CPR technique involves pushing hard and fast, at a rate of at least 100 compressions per minute and to a depth of at least 2 inches. It is also essential to allow chest recoil between compressions to enable proper blood circulation. Pausing CPR for drug administration would delay the delivery of continuous chest compressions, which are crucial for maintaining blood flow and oxygenation during cardiac arrest.

Correct answer:

Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from low blood oxygen levels. When a patient exhibits cyanosis, it indicates that their blood is poorly oxygenated, leading to a higher concentration of CO2 compared to oxygen. Options A and B are incorrect as cyanosis is associated with low oxygen levels, not hyperoxia or increased O2 saturation. Therefore, the correct answer is that patients exhibiting cyanosis will have blood levels of CO2 higher than O2 levels.

Correct answer:

The correct answer is HCV (Hepatitis C Virus). Hepatitis C is considered the most virulent bloodborne pathogen, being 100 times more virulent than Hepatitis B. HPV (Human Papillomavirus) is a sexually transmitted infection but is not a bloodborne pathogen. HIV (Human Immunodeficiency Virus) affects the immune system but is not as virulent as Hepatitis C in terms of bloodborne transmission. HBV (Hepatitis B Virus) is less virulent compared to HCV in the context of bloodborne transmission.
