Exam Cram NCLEX RN Practice Questions
1. When taking blood pressures on a variety of people at a health fair, what should the nurse keep in mind?
- A. After menopause, blood pressure readings in women are usually higher than those taken in men.
- B. The blood pressure of an African-American adult is usually higher than that of a non-Hispanic White adult of the same age.
- C. Blood pressure measurements in people who are overweight are usually higher than those of people who are at a normal weight.
- D. A teenager's blood pressure reading may be lower than that of an adult.
Correct answer: B
Rationale: When assessing blood pressures, it is important to consider that the blood pressure of African-American adults is typically higher than that of non-Hispanic White adults of the same age. This is significant as Black individuals in the United States have a higher prevalence of hypertension compared to other groups. Blood pressure readings in women are generally higher than in men after menopause. Additionally, blood pressure measurements in overweight individuals are typically higher than those in individuals of normal weight. While teenagers may have lower blood pressure readings than adults, it is crucial to recognize the trend of a gradual rise in blood pressure throughout childhood and into adulthood. Therefore, the correct choice is B. Choices A, C, and D are incorrect as they do not reflect the typical blood pressure differences observed in various populations.
2. When measuring a patient's body temperature, what factor should be considered that can influence the temperature?
- A. Constipation
- B. Diurnal cycle
- C. Nocturnal cycle
- D. Patient's emotional state
Correct answer: B
Rationale: When measuring body temperature, it is essential to consider factors that can influence it. The diurnal cycle, which refers to the body's natural temperature variations throughout a 24-hour period, can impact body temperature readings. Factors like exercise, age, and environment can also affect body temperature. Constipation does not directly influence body temperature. The 'nocturnal cycle' is not a recognized term in relation to body temperature. While a patient's emotional state can affect vital signs, it is not a primary factor in influencing body temperature measurements.
3. What are Korotkoff sounds?
- A. Sounds noted during diastole.
- B. The result of the vibration of blood against artery walls while blood pressure readings are being taken.
- C. Sounds only noted by skilled cardiologists.
- D. Distinct sounds which are classified into 6 phases.
Correct answer: B
Rationale: Korotkoff sounds are the sounds that occur when blood flows in an artery that has been temporarily compressed during a blood pressure measurement. These sounds result from the vibration of blood against the artery walls as the pressure cuff is released. There are five distinct phases of Korotkoff sounds, which healthcare providers are trained to identify during blood pressure assessment. The correct answer, choice B, accurately describes the nature of Korotkoff sounds and how they are generated. Choices A, C, and D are incorrect because Korotkoff sounds are not specific to diastole, not limited to skilled cardiologists, and categorized into five phases, not six.
4. Mr. and Mrs. K have just adopted a newborn infant and are preparing to take him home from the hospital for the first time. Which safety measure is most appropriate for the clients in this situation?
- A. Turn the handles of pans on the stove inward
- B. Set up a baby gate at the top of the stairs
- C. Cover electrical outlets with child-proof plugs
- D. Install an approved car seat that is facing backward in the back seat
Correct answer: D
Rationale: Parents of newborn infants should use an approved car seat that has been installed facing backward in the back seat of the car. Securing infants in car seats, even from the first ride home from the hospital, promotes safety while transporting. While safety measures at home such as baby gates or outlet covers are important, they are not the priority safety measures until the baby is old enough to be mobile. The car seat is crucial for protecting the newborn during transportation, ensuring proper positioning and restraint in the event of sudden stops or accidents. Turning handles of pans on the stove inward, setting up a baby gate, and covering electrical outlets are important safety measures at home but are not as critical for the immediate safety of a newborn during transportation.
5. Which statement by the client with chronic obstructive lung disease indicates an understanding of the major reason for the use of occasional pursed-lip breathing?
- A. ''This action of my lips helps to keep my airway open.''
- B. ''I can expel more air when I pucker up my lips to breathe out.''
- C. ''My mouth doesn't get as dry when I breathe with pursed lips.''
- D. ''By prolonging breathing out with pursed lips, the smaller areas in my lungs don't collapse.''
Correct answer: D
Rationale: The correct answer is D. Clients with chronic obstructive pulmonary disease have difficulty exhaling fully due to the weak alveolar walls from the disease process. Pursed-lip breathing helps prevent alveolar collapse by maintaining positive pressure in the airways during exhalation. This is the major reason for using pursed-lip breathing in individuals with chronic obstructive lung disease. Choices A, B, and C are incorrect because they do not directly address the main purpose of pursed-lip breathing, which is to prevent alveolar collapse and improve exhalation in these patients.
