1. What is a common error when taking a pulse?

A. Placing the index finger on the radial artery located on the thumb side of a patient's wrist.
B. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure.
C. Counting the pulse for 15 seconds and multiplying the number by four.
D. None of the above will cause errors.

Correct answer: C

Rationale: The correct answer is counting the pulse for 15 seconds and multiplying the number by four. To accurately assess a patient's heart rate or pulse, it is crucial to count the pulse for a full minute. Counting for only 15 seconds and then multiplying by four may result in an inaccurate heart rate calculation. This approach could miss arrhythmias or intermittent pulsations that could be vital indicators of the patient's condition. Placing the index finger on the radial artery, which is located on the thumb side of the patient's wrist, is the correct technique for taking a pulse. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure is a valid observation and not an error in itself. Therefore, the most common error in this scenario is incorrectly calculating the pulse rate by multiplying a 15-second count by four.

2. Mrs. D is a pregnant client who is 33 weeks' gestation and is admitted for bright red vaginal bleeding. Her physician suspects placenta previa. All of the following nursing interventions are appropriate for this client except:

A. Institute complete bed rest for the client
B. Assess uterine tone to determine condition
C. Perform a vaginal exam to assess cervical dilation
D. Measure and record blood loss each shift

Correct answer: C

Rationale: A client with placenta previa has part of the placenta covering some or all of the cervical opening. Performing a vaginal exam for placenta previa may cause significant bleeding and should be avoided unless directed by a physician, and preparations are made for emergency delivery. **Choice A** is correct as complete bed rest is essential to decrease the risk of further bleeding. **Choice B** is appropriate as assessing uterine tone helps in determining the condition of the uterus and can provide important information for the healthcare team. **Choice D** is also a necessary intervention as monitoring and recording blood loss is crucial in assessing the client's condition and response to treatment.

3. A patient has been told to monitor her LH levels. Which of the following potential conditions might the patient be suffering from?

A. Menorrhagia
B. Grave's Disease
C. Menopause
D. Infertility

Correct answer: D

Rationale: Luteinizing hormone (LH) is released by the pituitary gland to stimulate ovulation. One of the common reasons for monitoring LH levels is infertility. In women with infertility, LH levels are monitored to time intercourse accurately to maximize the chances of conception. Menorrhagia (choice A) is characterized by heavy menstrual bleeding and is not directly related to LH levels. Grave's Disease (choice B) is an autoimmune disorder affecting the thyroid gland and is not typically monitored by LH levels. Menopause (choice C) is a natural process marking the end of a woman's reproductive years and is not a condition where LH monitoring for infertility is common.

4. What should the nurse anticipate or expect of an American Indian woman seeking help to regulate her diabetes?

A. Will comply with the treatment prescribed.
B. Has given up her belief in naturalistic causes of disease.
C. May also be seeking the assistance of a shaman or medicine man.
D. Will need extra help in dealing with her illness and may be experiencing a crisis of faith.

Correct answer: C

Rationale: When caring for an American Indian patient seeking help for diabetes, the nurse should anticipate that the patient may also seek the assistance of a shaman or medicine man in addition to biomedical treatment. This cultural practice is common among American Indians who believe in holistic healing involving body, mind, and spirit. It is important for the nurse to acknowledge and respect these cultural beliefs and practices. Choice A is incorrect because patients from different cultures may not always comply with prescribed treatments due to various factors, including cultural beliefs. Choice B is incorrect as patients seeking traditional healing methods do not necessarily give up their beliefs in naturalistic causes of disease; instead, they often complement biomedical care. Choice D is incorrect as assuming the patient is experiencing a crisis of faith is not appropriate; it is more about respecting and understanding the patient's cultural background and beliefs.

5. Which of the following is a disadvantage of using a dry heat application?

A. Dry heat is more likely to cause burns than moist heat
B. Dry heat does not penetrate deeply into the tissues
C. Dry heat causes the skin to dry out more quickly
D. Dry heat can quickly cause skin breakdown

Correct answer: C

Rationale: The correct answer is that dry heat causes the skin to dry out more quickly. When comparing dry and moist heat applications, dry heat is less likely to cause burns and skin breakdown. However, one of the disadvantages of dry heat is that it does not penetrate deeply into the tissues and may lead to faster drying out of the skin. This can have negative effects on skin integrity and overall comfort during therapy. Choice A is incorrect because dry heat is less likely to cause burns than moist heat. Choice B is incorrect as dry heat may not penetrate deeply into tissues. Choice D is incorrect as dry heat is less likely to cause skin breakdown compared to moist heat.
