1. Which technique is correct when assessing the radial pulse of a patient?
- A. Palpate for 1 minute if the rhythm is irregular.
- B. Palpate for 15 seconds and multiply by 4 if the rhythm is regular.
- C. Palpate for 2 full minutes to detect any variation in amplitude.
- D. Palpate for 10 seconds and multiply by 6 if the rhythm is regular and the patient has no history of cardiac abnormalities.
Correct answer: A
Rationale: When assessing the radial pulse, if the rhythm is irregular, the pulse should be counted for a full minute to get an accurate representation of the pulse rate. In cases where the rhythm is regular, the recommended technique is to palpate for 15 seconds and then multiply by 4 to calculate the beats per minute. This method is more accurate and efficient for normal or rapid heart rates. Palpating for 30 seconds and multiplying by 2 is not as effective, as any error in counting results in a larger discrepancy in the calculated heart rate. Palpating for 2 full minutes is excessive and not necessary for routine pulse assessment. Palpating for 10 seconds and multiplying by 6 is not a standard technique and may lead to inaccuracies, especially in patients with cardiac abnormalities.
2. The nurse informs the physical therapy department that the client is too weak to use a walker and needs to be transported by wheelchair. Which step of the nursing process is the nurse engaged in at this time?
- A. Assessment
- B. Planning
- C. Implementation
- D. Evaluation
Correct answer: C
Rationale: The nurse is responsible for coordinating the plan of care with other disciplines to ensure the client's safety. This action represents the implementation phase of the nursing process. During the implementation phase, the nurse puts the care plan into action, which includes coordinating with other healthcare team members like the physical therapy department. Assessment involves data gathering, planning involves goal setting, and evaluation involves determining the attainment of client goals.
3. A client has died approximately one hour ago. The nurse notes that the client's temperature has decreased in the last hour since their death. Which of the following processes explains this phenomenon?
- A. Rigor mortis
- B. Postmortem decomposition
- C. Algor mortis
- D. Livor mortis
Correct answer: C
Rationale: Algor mortis occurs after death when the body's circulation stops, and the client's temperature begins to fall. The client's temperature will drop by approximately 1.8 degrees per hour until it reaches room temperature. During algor mortis, the client's skin gradually loses its elasticity. Rigor mortis refers to the stiffening of the body after death due to chemical changes in the muscles. Postmortem decomposition is the breakdown of tissues after death. Livor mortis is the pooling of blood in the dependent parts of the body, causing a purple-red discoloration.
4. Which acronym would BEST describe the procedure for assessing a patient that appears unconscious?
- A. WBC
- B. QRS
- C. XYZ
- D. ABC
Correct answer: D
Rationale: The correct answer is D, 'ABC.' The ABC method stands for Airway, Breathing, Circulation. When encountering an unconscious patient, it is crucial to first ensure their Airway is clear by performing the 'head tilt, chin lift' maneuver. Next, assess Breathing by observing for chest rise and fall, listening for breath sounds, and feeling for airflow. Finally, check for Circulation by assessing for a pulse. Choices A, B, and C ('WBC,' 'QRS,' 'XYZ') are incorrect as they do not represent the standard approach to assessing an unconscious patient.
5. Where is the Loop of Henle located in the body?
- A. Liver
- B. Kidney
- C. Heart
- D. Ear
Correct answer: B
Rationale: The Loop of Henle is a crucial structure found in the kidneys. It plays a vital role in the concentration of urine by creating a concentration gradient in the renal medulla. Choices A, C, and D are incorrect because the Loop of Henle is not located in the liver, heart, or ear. Understanding the anatomical location of the Loop of Henle is essential in comprehending renal physiology and the mechanism of action of diuretic medications.
