An allergic reaction is classified as what type of pharmacological effect?
- A. a therapeutic effect
- B. a side effect
- C. an adverse effect
- D. an incompatibility
Correct Answer: C
Rationale: An allergic reaction is classified as an adverse effect because it is an unintended response to a medication that requires treatment. A side effect is an undesired but somewhat expected reaction to a drug that does not necessarily need intervention. Incompatibility refers to an unsuitable combination of substances that leads to an adverse effect. A therapeutic effect is the desired and intended outcome of a medication.

The LPN needs to determine the client's respiratory rate. What is the best technique to do this?
- A. Tell the client you need to count their respiratory rate.
- B. Subtly watch the client from across the room when they are doing an activity.
- C. Ask the client to sit still for 30 seconds.
- D. Count respirations while pretending to check the client's pulse.
Correct Answer: D
Rationale: The best technique to determine a client's respiratory rate is to count respirations while pretending to check the client's pulse. You should not inform the client that you are counting their respirations, as this might lead to a change in their breathing pattern. Pretending to check the pulse allows you to be close to the client without revealing that you are assessing their respiratory rate. Asking the client to sit still may not be as effective, as it may cause them to concentrate on their breathing. Watching from across the room may not provide an accurate assessment of respirations, as they might be difficult to observe.
A nurse is preparing to screen a client's vision with the use of a Snellen chart. The nurse uses which technique?
- A. Tests the right eye, then tests the left eye, and finally tests both eyes together
- B. Assesses both eyes together, then assesses the right and left eyes separately
- C. Asks the client to stand 40 feet from the chart and read the largest line on the chart
- D. Asks the client to stand 40 feet from the chart and read the line that can be read 200 feet away by someone with unimpaired vision
Correct Answer: A
Rationale: To test visual acuity with the use of a Snellen chart, the nurse places the chart in a well-lit spot at the client's eye level, with the client positioned exactly 20 feet from the chart. The client shields one eye at a time with an opaque card during the test. After testing each eye separately, both eyes are assessed together. The client is asked to read the smallest line of letters visible and encouraged to read the next smallest line as well. Therefore, option A is correct as it describes the correct technique of testing one eye at a time before assessing both eyes together. Option B is incorrect as it assesses both eyes together first, which is not the standard procedure. Options C and D are incorrect as they suggest standing 40 feet from the chart, which contradicts the standard distance of 20 feet for a Snellen chart test.
A nurse is reviewing a patient's current Lithium levels. Which of the following values is outside the therapeutic range?
- A. 1.0 mEq/L
- B. 1.1 mEq/L
- C. 1.2 mEq/L
- D. 1.3 mEq/L
Correct Answer: D
Rationale: 1.0-1.2 mEq/L is considered standard therapeutic range for patient care.
When preparing to assist the healthcare provider in examining a client's skin with the use of a Wood light, what action should the nurse perform?
- A. Darken the room
- B. Obtain informed consent from the client
- C. Obtain a scalpel and a slide for diagnostic evaluation
- D. Obtain medication to anesthetize the skin area before proceeding with the examination
Correct Answer: A
Rationale: When using a Wood light during a skin examination, the room should be darkened to enhance the visibility of fluorescence. The Wood light emits long-wavelength ultraviolet light, highlighting certain skin conditions. Darkening the room aids in better visualization. Obtaining informed consent is a crucial aspect of healthcare but not directly related to using a Wood light. Obtaining a scalpel and a slide is unnecessary for a noninvasive Wood light examination. Anesthetizing the skin area is not required as the procedure is painless and noninvasive.
What are the basic reasons American families are having difficulty adequately performing their vital health care function?
- A. structure of the health care system and family structure
- B. psychological factors affecting men and women seeking health care
- C. conditions labeled as disabilities and considered too time-consuming
- D. health care organizations (HMOs) and disconnected families
Correct Answer: A
Rationale: The correct answer is the 'structure of the health care system and family structure'. Scholars suggest that the reasons families are having difficulty providing health care for their members lie with both the structure of the health care system and the family structure. Major factors explaining differences in utilization patterns of medical services include the lack of healthcare insurance coverage, lack of services for special populations (such as teenage males), perception by families of the health care system and the health care provider, and lack of partnership between health care providers and families in mutually addressing health care issues. Choices B, C, and D are incorrect as they do not address the fundamental reasons related to the health care system and family structure as discussed in the provided extract.
