NCLEX RN Exam Preview Answers
1. The nurse is unable to palpate the right radial pulse on a patient. What would the nurse do next?
- A. Auscultate over the area with a fetoscope.
- B. Use a goniometer to measure the pulsations.
- C. Use a Doppler device to check for pulsations over the area.
- D. Check for the presence of pulsations with a stethoscope.
Correct answer: C
Rationale: When a nurse is unable to palpate a radial pulse, the next step is to use a Doppler device to check for pulsations over the area. Doppler devices are specifically designed to augment pulse or blood pressure measurements. Auscultating with a fetoscope is used to listen to fetal heart tones and is not relevant in this scenario. Goniometers are used to measure joint range of motion and are not used to assess pulses. Stethoscopes are primarily used to auscultate breath, bowel, and heart sounds, not to check for pulsations in peripheral pulses. Therefore, the correct course of action when unable to palpate a pulse is to utilize a Doppler device to assess for pulsations in the radial pulse area.
2. The nurse supervises unlicensed assistive personnel (UAP) who are providing care for a patient with right lower lobe pneumonia. The nurse should intervene if which action by UAP is observed?
- A. UAP splint the patient's chest during coughing.
- B. UAP assist the patient to ambulate to the bathroom.
- C. UAP help the patient to a bedside chair for meals.
- D. UAP lower the head of the patient's bed to 15 degrees.
Correct answer: D
Rationale: The correct action for the nurse to intervene in is when the UAP lowers the head of the patient's bed to 15 degrees. This position can decrease ventilation in a patient with pneumonia, potentially worsening their condition. Choices B and C involve assisting the patient with activities of daily living and promoting mobility, which are appropriate for the patient's care. Choice A, splinting the patient's chest during coughing, can help the patient manage coughing effectively, which is also appropriate for a patient with pneumonia.
3. When reviewing the demographics of ethnic groups in the United States, which group does the nurse recall as the largest and fastest-growing population?
- A. Asian
- B. Hispanic
- C. American Indian
- D. African American/Black
Correct answer: B
Rationale: The correct answer is 'Hispanic.' Hispanics are the largest and fastest-growing population in the United States. While African Americans/Blacks, Asians, American Indians, and other groups are significant, Hispanics currently represent the largest demographic group. African American/Black, Asian, and American Indian populations are substantial but not as large or fast-growing as the Hispanic population. Therefore, Hispanic is the most appropriate choice in this scenario.
4. An experienced healthcare professional instructs a new colleague on caring for a patient with dyspnea due to a pulmonary fungal infection. Which action by the new colleague indicates a need for further teaching?
- A. Listening to the patient's lung sounds several times during the shift
- B. Placing the patient in droplet precautions and in a private hospital room
- C. Increasing the oxygen flow rate to maintain oxygen saturation above 90%
- D. Monitoring the patient's serology results to identify the specific infecting organism
Correct answer: B
Rationale: The correct answer is placing the patient in droplet precautions and in a private hospital room. Fungal infections are not transmitted from person to person, so isolation procedures like droplet precautions are unnecessary. Listening to the patient's lung sounds, increasing the oxygen flow rate, and monitoring serology results are all appropriate actions in caring for a patient with dyspnea caused by a pulmonary fungal infection.
5. Which of the following descriptions best describes the function of the thyroid gland?
- A. The thyroid gland converts glucose into glycogen
- B. The thyroid gland secretes cortisol during times of stress
- C. The thyroid gland regulates body metabolism
- D. The thyroid gland affects skin pigmentation
Correct answer: C
Rationale: The thyroid gland is responsible for secreting thyroxine (T4) and triiodothyronine (T3), which work to regulate the metabolism of the body's cells. The primary function of the thyroid gland is to control the body's metabolic rate, affecting processes such as heart rate, temperature regulation, and energy levels. Choices A, B, and D are incorrect because the thyroid gland is not involved in converting glucose into glycogen, secreting cortisol, or affecting skin pigmentation. Instead, the primary role of the thyroid gland is to regulate the metabolism and energy balance in the body.
