1. An individual with which of the following blood type can receive only blood of that same type?
- A. Type O
- B. Type A
- C. Type B
- D. Type AB
Correct answer: Type O
Rationale: The correct answer is Type O. Individuals with blood type O can only receive blood from donors with blood type O. This is because type O blood lacks both A and B antigens, so if a person with type O blood receives blood with A, B, or AB antigens, their immune system will recognize these as foreign substances and attack them. Choices B, C, and D are incorrect because individuals with type A can receive blood from A or O donors, individuals with type B can receive blood from B or O donors, and individuals with type AB can receive blood from A, B, AB, or O donors.
2. The nurse is preparing to administer a vaccine to a newborn. Before administering the vaccine, the nurse should
- A. warm the vaccine to room temperature.
- B. gently cleanse the chosen injection site.
- C. check the infant's temperature.
- D. administer the full dose at a single injection site.
Correct answer: C
Rationale: Before administering a vaccine to a newborn, it is essential for the nurse to check the infant's temperature. This is important to ensure that the newborn does not have a fever, which could indicate an underlying infection or illness. Warming the vaccine to room temperature is not necessary and could be harmful. Vigorously massaging the injection site is not recommended as it can cause discomfort and tissue damage. Dividing the dose for administration to three injection sites is not standard practice for vaccine administration to a newborn.
3. Does the diaphragm separate the thoracic and abdominopelvic cavities?
- A. True
- B. False
- C. Not Sure
- D. None of the above
Correct answer: A
Rationale: The correct answer is A: True. The diaphragm is a dome-shaped muscle that separates the thoracic cavity, which contains the heart and lungs, from the abdominopelvic cavity, which contains organs such as the stomach, liver, and intestines. It plays a crucial role in breathing by contracting and relaxing to help with the process of respiration. Therefore, the statement is accurate. Choice B is incorrect because the diaphragm indeed separates these two cavities. Choice C is incorrect as the information provided allows one to determine the correct answer. Choice D is incorrect as the correct answer is 'True.'
4. Nurse DMLM is correct in identifying the correct sequence of events during abdominal assessment if she identifies which of the following?
- A. Inspection, Auscultation, Percussion, Palpation
- B. Inspection, Percussion, Palpation, Auscultation
- C. Inspection, Palpation, Percussion, Auscultation
- D. Inspection, Auscultation, Palpation, Percussion
Correct answer: D
Rationale: The correct sequence for abdominal assessment is Inspection, Auscultation, Percussion, Palpation. Start with Inspection to observe any visible abnormalities, followed by Auscultation to listen for bowel sounds, then Percussion to assess the density of underlying structures, and finally Palpation to feel for any tenderness or masses. Choices A, B, and C have the incorrect sequence of assessment techniques.
5. A woman has been prescribed Climara, a transdermal estradiol patch. Which of the following should she be instructed by the nurse regarding the administration?
- A. Avoid prolonged sun exposure at the patch site due to increased plasma concentrations.
- B. The application of heat at the patch site will decrease effectiveness and result in pregnancy.
- C. The medication, when exposed to sunlight, can increase the risk of breast cancer.
- D. Exposure of the medication to occasional cold will increase effectiveness with application.
Correct answer: A
Rationale: The correct answer is A. The Climara patch delivers estradiol transdermally, and patients should be instructed to avoid prolonged sun exposure at the patch site due to increased plasma concentrations. Sun exposure can accelerate the absorption of the medication, leading to higher systemic levels than intended. Choices B, C, and D are incorrect because heat at the patch site does not result in pregnancy but may alter absorption rates, there is no direct link between sunlight exposure and breast cancer risk related to this medication, and exposure to cold does not increase effectiveness of the transdermal patch.
