What type of sampling wills Nurse Sandy adopts 11 when every third (3rd) patients with MI are selected after a random start?
- A. Simple random
- B. Stratified
- C. Systematic
- D. Cluster
Correct Answer: C
Rationale: The correct answer is C: Systematic sampling. Nurse Sandy is adopting systematic sampling by selecting every third patient with MI after a random start. This method ensures equal chance of selection for each patient and maintains randomness. In contrast, simple random sampling (A) entails each patient having an equal chance of being selected independently. Stratified sampling (B) divides patients into groups based on certain characteristics, which is not the case here. Cluster sampling (D) involves grouping patients and selecting entire groups, which is different from the individual selection in this scenario.

Which of the following dental conditions is characterized by the wearing away of tooth structure due to friction from external sources such as toothbrushing or abrasive toothpaste?
- A. Dental caries
- B. Attrition
- C. Abrasion
- D. Erosion
Correct Answer: C
Rationale: The correct answer is C: Abrasion. Abrasion is the wearing away of tooth structure due to friction from external sources like toothbrushing or abrasive toothpaste. Dental caries (A) refers to tooth decay caused by bacteria. Attrition (B) is the wearing down of tooth structure due to tooth-to-tooth contact. Erosion (D) is the loss of tooth structure from acid attacks, not friction. Therefore, option C is the most fitting choice based on the description given.
A patient receiving palliative care for end-stage cancer experiences intractable pain despite receiving opioid medications. What intervention should the palliative nurse prioritize to address the patient's pain?
- A. Increase the dosage of the current opioid medication.
- B. Switch to a different opioid medication with a different potency.
- C. Administer adjuvant analgesic medications to enhance pain relief.
- D. Refer the patient to a pain management specialist for evaluation.
Correct Answer: D
Rationale: The correct answer is D because referring the patient to a pain management specialist for evaluation is essential in this scenario. The specialist can conduct a comprehensive assessment to identify the underlying causes of the intractable pain and recommend a tailored pain management plan. This approach ensures a multidisciplinary approach to address the complex nature of the patient's pain.
Choice A is incorrect because simply increasing the dosage of the current opioid medication may not effectively address the underlying cause of the pain and can lead to potential side effects or opioid tolerance.
Choice B is incorrect as switching to a different opioid medication without a thorough evaluation may not guarantee better pain control and can increase the risk of adverse effects or inadequate pain relief.
Choice C is incorrect as administering adjuvant analgesic medications without addressing the root cause of the pain may not provide adequate pain relief and does not address the need for a specialized pain management plan.
In providing tracheostomy care which of the following is the nurse's PRIORITY nursing action? The nurse ________.
- A. Cuts the dressing using sterile scissors
- B. Clean the incisions with iodine-based antiseptic
- C. Secures clean ties before removing soiled ones
- D. Uses clean technique
Correct Answer: C
Rationale: The correct answer is C: Secures clean ties before removing soiled ones. This is the priority action because securing clean ties prevents accidental dislodgement of the tracheostomy tube, ensuring the patient's airway remains patent. Cutting the dressing (A) or cleaning the incisions (B) can be important but not as critical as securing the tube. Using clean technique (D) is essential but not the priority in this situation.
Which of the following cell types is primarily responsible for presenting antigens to T cells during the immune response?
- A. B cells
- B. Natural killer (NK) cells
- C. Macrophages
- D. Eosinophils
Correct Answer: C
Rationale: The correct answer is C: Macrophages. Macrophages are antigen-presenting cells that engulf pathogens and present their antigens to T cells, initiating an immune response. They express major histocompatibility complex (MHC) molecules necessary for T cell recognition. B cells also present antigens but primarily to B cells for antibody production. NK cells are involved in killing infected cells, not antigen presentation. Eosinophils are mainly involved in allergic responses and defense against parasites, not antigen presentation.
Which of the following situation is an example of incongruent message?
- A. When the nurse means what she says
- B. When the words and behavior of the nurse agree
- C. When what the nurse says and does do not agree
- D. When content and process agree
Correct Answer: C
Rationale: Step 1: Incongruent message occurs when verbal and nonverbal communication do not align.
Step 2: Choice C states "When what the nurse says and does do not agree," indicating a lack of alignment.
Step 3: This inconsistency can lead to confusion or mistrust in communication.
Step 4: Choices A, B, and D all describe situations with alignment between words and actions, making them congruent.
Summary: Choice C is correct as it exemplifies incongruent communication, while Choices A, B, and D are incorrect as they describe congruent messages.
