Extract:
Question 1 of 5
A nurse is caring for a client who has a prescription for a stool guaiac test. The client asks the nurse about the purpose of the test. The nurse should respond by stating that the stool guaiac is testing for which of the following findings in the client's feces?
Correct Answer: C
Rationale: The correct answer is C: Blood. The stool guaiac test is used to detect the presence of hidden blood in the feces, which may indicate gastrointestinal bleeding. The rationale is as follows: 1. The test is based on the principle that blood in the stool can be detected by a chemical reaction that triggers a color change when guaiac is added. 2. By identifying blood in the stool, healthcare providers can investigate potential causes such as ulcers, polyps, or colorectal cancer. 3.
Choices A, B, and D are incorrect because the stool guaiac test specifically targets blood, not bacteria, parasites, or fat.
Question 2 of 5
A nurse is evaluating an older adult client who is receiving end-of-life care and has Cheyne-Stokes respirations. Which of the following observations should the nurse identify as confirmation of this respiratory pattern?
Correct Answer: A
Rationale: The correct answer is A because Cheyne-Stokes respirations are characterized by a pattern of breathing that ranges from very deep to very shallow with periods of apnea. This pattern reflects an abnormal breathing pattern often seen in end-of-life care. Shallow breathing alternating with periods of apnea (
Choice
B) is incorrect as it does not fully capture the range of depth in breathing associated with Cheyne-Stokes respirations. Rapid respirations that are unusually deep and regular (
Choice
C) do not align with the irregular pattern of Cheyne-Stokes respirations. An inability to breathe without dyspnea unless sitting upright (
Choice
D) describes orthopnea, which is not characteristic of Cheyne-Stokes respirations.
Question 3 of 5
A nurse is measuring an adult client's tympanic temperature. Which of the following actions should the nurse take?
Correct Answer: C
Rationale: The correct answer is C: Aim the probe posteriorly in the direction of the eardrum. This is the correct action when measuring tympanic temperature as it ensures accurate reading by aligning the probe with the eardrum. Removing cerumen with a cotton-tipped applicator (
A) is not necessary for temperature measurement. Pulling the pinna downward and backward (
B) is incorrect as it can obstruct the ear canal. Inserting the probe with a circular motion (
D) can cause discomfort and inaccurate readings.
Question 4 of 5
A nurse is collecting data about a client's pulmonary system. While auscultating the client's lungs, the nurse hears continuous gurgling, low-pitched sounds over the trachea and bronchi. Which of the following terms should the nurse use to document this finding?
Correct Answer: A
Rationale: The correct answer is A: Rhonchi. Rhonchi are continuous gurgling, low-pitched sounds heard over the trachea and bronchi. This indicates the presence of secretions or mucus in the airways. Crackles (
B) are discontinuous, high-pitched sounds heard during inspiration and indicate fluid in the alveoli. Wheezing (
C) is a high-pitched musical sound heard during expiration, indicating narrowed airways. Friction rub (
D) is a harsh, grating sound heard during inspiration and expiration, indicating inflammation of the pleural surfaces. The other choices do not match the description provided in the question, making them incorrect.
Question 5 of 5
A nurse is caring for a client who has respiratory acidosis. Which of the following pH levels should the nurse expect?
Correct Answer: A
Rationale:
Correct Answer: A (pH 7.31)
Rationale:
1. Respiratory acidosis is caused by inadequate ventilation, leading to CO2 retention and decreased pH.
2. In respiratory acidosis, the pH decreases below the normal range of 7.35-7.45.
3. A pH of 7.31 indicates acidosis, which aligns with the client's condition.
4. pH levels of 7.39, 7.48, and 7.50 are within the normal range, ruling out choices B, C, and D as incorrect.
