Nursing Elites

1. Why is a pulse oximeter attached to Mr. Dizon's finger?

• A. To determine if the patient's hemoglobin level is low and if he requires a blood transfusion
• B. To check the level of the patient's tissue perfusion
• C. To measure the effectiveness of the patient's anti-hypertensive medications
• D. To detect oxygen saturation of arterial blood before symptoms of hypoxemia develop

Correct answer: D

Rationale: A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.

2. Which hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?

• A. glucagon
• B. ghrelin
• C. leptin
• D. insulin

Correct answer: C

Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.

3. What are sheets/forms that provide an efficient and time-saving way to record information that must be obtained repeatedly at regular and/or short intervals of time? This does not replace progress notes; instead, it records information on vital signs, intake and output, treatment, postoperative care, postpartum care, and diabetic regimen, etc. These are used whenever specific measurements or observations need to be documented repeatedly. What is this?

• A. Nursing Kardex
• B. Graphic Flow Sheets
• C. Discharge Summary
• D. Medicine and Treatment Record

Correct answer: A

Rationale: The correct answer is A, Nursing Kardex. Nursing Kardex is a tool used for documenting essential patient information that needs to be recorded repeatedly at regular intervals. It includes vital signs, intake and output, treatment details, postoperative care, postpartum care, and diabetic regimen. This tool is efficient and time-saving for healthcare professionals. Choice B, Graphic Flow Sheets, may be used for visual representation of patient data but is not specifically designed for repeated documentation of essential information. Choice C, Discharge Summary, is a document outlining the patient's care and condition at the time of discharge, not for repeated recording of ongoing data. Choice D, Medicine and Treatment Record, focuses more on specific medications and treatments rather than a comprehensive recording of various patient data needed at regular intervals.

4. A nurse is reviewing the medication administration record for a client who is 2 days postoperative following abdominal surgery. The nurse should recognize that which of the following medications places the client at risk for wound dehiscence?

• A. Omeprazole
• B. Zolmitriptan
• C. Prednisone
• D. Verapamil

Correct answer: C

Rationale: Corrected Rationale: Prednisone is a corticosteroid that can impair wound healing and increase the risk of wound dehiscence. Omeprazole (Choice A) is a proton pump inhibitor used to reduce stomach acid production and does not directly impact wound healing. Zolmitriptan (Choice B) is a medication used to treat migraines and does not affect wound healing. Verapamil (Choice D) is a calcium channel blocker used to treat high blood pressure and certain heart conditions, and it does not pose a significant risk for wound dehiscence.

5. What activities best describe the work of the placenta during pregnancy?

• A. surrounding and cushioning the fetus
• B. combining maternal and fetal blood stores to exchange nutrients
• C. producing hormones that maintain the pregnancy
• D. absorbing vitamins and minerals that can be transferred to the fetus

Correct answer: C

Rationale: The placenta plays a crucial role in producing hormones that are necessary for maintaining pregnancy, supporting fetal development, and preparing the mother's body for childbirth. Choices A, B, and D are incorrect because the placenta's primary function is not to surround and cushion the fetus, combine blood stores for nutrient exchange, or absorb vitamins and minerals. While the placenta does facilitate the exchange of nutrients and oxygen between the mother and fetus, its hormone production is the most critical function during pregnancy.
