Exam Cram NCLEX RN Practice Questions

1. Which of the following white blood cells is the smallest and can be involved in humoral immunity?

Correct answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.

2. Plantar flexion can be prevented with ________________.

Correct answer: B

Rationale: Plantar flexion, or foot drop, can be prevented with foot boards, special splints, and range of motion exercises. Foot boards help maintain the foot in a neutral position, preventing contractures and deformities. Foot soaks (choice A) may help with foot hygiene but do not directly prevent plantar flexion. Toenail care (choice C) is important for overall foot health but does not prevent plantar flexion. Proper shoes (choice D) are essential for foot support and comfort but do not specifically prevent plantar flexion.

3. Which risk factor places patients and residents at the greatest risk for falls?

Correct answer: A

Rationale: Old age is a significant risk factor for falls as elderly individuals are more prone to falls due to factors like decreased balance, muscle strength, and vision. Middle age is less associated with falls compared to old age. Pneumonia and COPD are medical conditions that are not direct risk factors for falls, unlike aging which significantly increases the risk of falls.

4. A physician is explaining a procedure to a patient that may cure her recurring Staph infection. The doctor explains how the procedure is done, what to expect, the odds of the procedure curing the infection, and possible side effects and risks. The physician is:

Correct answer: A

Rationale: The correct answer is preparing the patient to give informed consent. Giving informed consent is the process of providing a patient with all necessary information about a medical procedure, including how it's done, what to expect, the likelihood of success, and potential risks and side effects. This allows the patient to make an informed decision about their treatment. Protecting HIPAA (Health Insurance Portability and Accountability Act) involves safeguarding patient health information and is not directly related to the scenario described. It is important for physicians to inform patients of any alternative therapies available to them to ensure they have all relevant information to make a decision regarding their treatment. Therefore, choice C, 'Not required to inform the patient of any alternative therapies,' is incorrect. Choice D, 'None of the above,' is incorrect as the physician is indeed preparing the patient for informed consent.

5. Mary T. was admitted to a nursing home on May 1st. On July 4th, she was diagnosed with a skin infection. This infection is considered a ________________ infection.

Correct answer: A

Rationale: The correct answer is 'nosocomial.' A nosocomial infection is defined as one that is not present upon admission to a healthcare facility but instead occurs during the patient's stay. In this case, since Mary was diagnosed with a skin infection after being admitted to the nursing home, it is considered a nosocomial infection. Nosocomial infections are a significant concern in healthcare settings, and infection control measures are in place to prevent their spread. Choices B, C, and D are incorrect. 'Systemic' refers to a condition affecting the entire body, not specific to a healthcare setting. 'Resident flora' and 'resident aura' are not commonly used terms in healthcare and do not relate to infections acquired in healthcare facilities.
