1. What is the flap of tissue that covers the trachea upon swallowing called?

A. Epidermis
B. Endocardium
C. Epiglottis
D. Epistaxis

Correct answer: C

Rationale: The correct answer is C: Epiglottis. The epiglottis is a flap of tissue that covers the trachea when swallowing to prevent food or liquid from entering the airway. Choice A, Epidermis, is the outer layer of the skin and is not related to the trachea. Choice B, Endocardium, is the inner lining of the heart chambers and is also unrelated to the trachea. Choice D, Epistaxis, refers to a nosebleed and is not the correct term for the tissue covering the trachea.

2. Intermittent fevers are:

A. fevers which come and go.
B. fevers which rise and fall but are always considered above the patient's average temperature.
C. fevers which fluctuate more than three degrees and never return to normal.
D. None of the above.

Correct answer: A

Rationale: Intermittent fevers are characterized by periods of fever followed by periods of normal body temperature. They alternate between being febrile and afebrile. Continuous fevers show minimal fluctuations over a 24-hour period, while remittent fevers fluctuate significantly but do return to normal body temperature. Choice A is correct as it accurately describes intermittent fevers. Choices B and C are incorrect as they do not fully capture the defining characteristic of intermittent fevers, which involve cyclical episodes of fever and normal temperature. Choice D is incorrect as there is a specific definition for intermittent fevers.

3. When assessing the pulse of a 6-year-old patient, the nurse notices that the heart rate varies with the respiratory cycle, speeding up at the peak of inspiration and slowing to normal with expiration. What action would the nurse take next?

A. Notify the physician.
B. Record this finding as normal.
C. Check the child's blood pressure and note any variation with respiration.
D. Document that this child has bradycardia and continue with the assessment.

Correct answer: B

Rationale: The correct action for the nurse to take next is to record this finding as normal. Sinus dysrhythmia, characterized by heart rate variation with the respiratory cycle, is commonly found in children and young adults. The heart rate speeds up at the peak of inspiration and slows to normal with expiration. This phenomenon is a normal variant and does not require any intervention. There is no need to notify the physician as this finding is within the expected range for this age group. Checking the child's blood pressure for variations with respiration or documenting the child as having bradycardia would not be appropriate in this case, as sinus dysrhythmia is a normal physiological response.

4. Which of the following situations indicates the need to file an incident report?

A. The neon sign directing parking for visitors has burned out
B. A nurse must send a syringe pump to maintenance for annual service
C. A client's blood pressure dropped to 90/55 after receiving a dose of morphine
D. A client's spouse becomes angry and is asked to leave the premises

Correct answer: D

Rationale: An incident report is necessary for documenting unexpected events that occur in a healthcare setting. Situations that warrant filing an incident report include client accidents, medication errors, security problems, or disruptive behaviors that involve clients, families, or visitors. In this scenario, when a client's spouse displays disruptive behavior and is asked to leave the premises, it is essential to document this incident to ensure a record of the event and its resolution. Choices A, B, and C do not involve disruptive behavior or safety concerns that would require an incident report to be filed.

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.
