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.

What is the most useful patient position for proctologic exams?
- A. Trendelenburg
- B. Semi-Fowler's
- C. Full Fowler's
- D. Jack Knife
Correct Answer: D
Rationale: The Jack Knife position is the most useful for proctologic exams as it allows the patient to lie face down while keeping the buttocks elevated, providing optimal access for the examination. The Trendelenburg position, characterized by the body being laid flat with the feet higher than the head, is not suitable for proctologic exams. Semi-Fowler's and Full Fowler's positions are typically utilized for respiratory or cardiovascular conditions and are not ideal for proctologic examinations due to their lack of optimal access to the perianal area.
What term is used to describe the sexual response changes among middle-aged men?
- A. Menopause
- B. Climacteric
- C. Generativity
- D. Maturity
Correct Answer: B
Rationale: The correct answer is 'Climacteric.' Climacteric specifically refers to the period in middle-aged men characterized by sexual response changes, such as delayed arousal. Menopause, choice A, is incorrect as it is specific to women and marks the cessation of menstrual periods. Generativity, choice C, is unrelated as it refers to the concern for guiding the next generation. Maturity, choice D, is too broad and generally refers to reaching the adult stage of development, not specifically addressing sexual response changes in middle-aged men.
The most accurate reading for a temperature is done:
- A. Orally
- B. Aurally through a clean canal
- C. Rectally
- D. Axially
Correct Answer: B
Rationale: Aural readings are done through the ear canal. The tympanic membrane shares a blood supply with the hypothalamus, the brain area that regulates body temperature. Taking the temperature aurally through a clean canal ensures an accurate reading.
Choice A (Orally) is not the most accurate method for temperature measurement as it can be affected by external factors like drinking hot or cold liquids. Choice C (Rectally) is invasive and less practical for routine temperature monitoring. Choice D (Axially) is not a standard method for temperature measurement and may not provide accurate results.
An older adult patient brought to the emergency department by a family member is wandering outside, saying, "I can't find my way home."? The patient is confused and unable to answer questions. What is the nurse's best action?
- A. Document the patient's mental status and obtain other assessment data from the family member.
- B. Record the patient's answers to questions on the nursing assessment form.
- C. Ask an advanced practice nurse to perform the assessment interview.
- D. Call for a mental health advocate to maintain the patient's rights.
Correct Answer: A
Rationale: In this scenario, the patient is confused and unable to answer questions. When the patient is unable to provide information, it is important to use secondary sources such as family members. The nurse's best action is to document the patient's mental status and obtain additional assessment data from the family member. This approach will help gather relevant information about the patient's condition. Asking an advanced practice nurse to perform the assessment interview is not necessary as it is within the staff nurse's scope of practice. Calling for a mental health advocate is also unnecessary at this point as the priority is to assess the patient's condition and gather information from the family member.
What procedure examines a portion of the large intestine with an endoscope?
- A. Colposcopy
- B. Sigmoidoscopy
- C. Upper GI
- D. Cardiac catheterization
Correct Answer: B
Rationale: Sigmoidoscopy is the correct answer because it specifically examines the sigmoid colon located in the descending colon using an endoscope inserted through the rectum. This procedure captures video and images of the large intestine's lining, helping in the diagnosis of conditions like inflammatory bowel disease or colorectal cancer. Colposcopy, on the other hand, is a procedure for examining the cervix and vagina, not the large intestine. Upper GI involves capturing images of the esophagus and stomach, focusing on the upper gastrointestinal tract, not the large intestine. Cardiac catheterization is a procedure that involves threading a thin instrument through the femoral artery to the heart, used for cardiac interventions and not related to examining the large intestine.
