Fundamentals of Nursing HESI
1. A healthcare professional is reviewing a client's medication prescription, which reads, 'digoxin 0.25 by mouth every day.' Which of the following components of the prescription should the healthcare professional question?
- A. the medication
- B. the route
- C. the dose
- D. the frequency
Correct answer: C
Rationale: The healthcare professional should question the dose indicated in the prescription. In this case, '0.25' is incomplete without a unit of measurement, such as mg (milligrams). Without a specified unit, the dose lacks the necessary information for accurate administration. Choices A, B, and D are not incorrect components to question in medication prescriptions; however, in this scenario, the incompleteness of the dose is the most critical concern that needs clarification to ensure safe and effective medication administration.
2. When administering otic ear medication to an adult client, what action should be done to ensure the medication reaches the inner ear?
- A. Press gently on the tragus of the client’s ear.
- B. Pull the ear lobe up and back.
- C. Insert the medication deeply into the ear canal.
- D. Massage the ear gently after administering the medication.
Correct answer: A
Rationale: The correct action to ensure the medication reaches the inner ear is to press gently on the tragus of the client’s ear. The tragus is the small pointed eminence of the external ear, and pressing on it helps direct the medication deeper into the ear canal. Pulling the ear lobe up and back (Choice B) is the correct technique for administering eardrops to a child, not an adult. Inserting the medication deeply into the ear canal (Choice C) can cause injury or discomfort as the eardrops are designed to flow into the ear canal naturally. Massaging the ear gently after administering the medication (Choice D) is unnecessary and may not help the medication reach the inner ear effectively.
3. What is the process in which the double helix of deoxyribonucleic acid (DNA) duplicates?
- A. Amniocentesis
- B. Mitosis
- C. Meiosis
- D. Mutation
Correct answer: B
Rationale: Mitosis is the correct answer because it is the process of cell division in which a cell duplicates its DNA and divides into two identical daughter cells. During mitosis, the DNA is replicated, and each daughter cell receives an identical copy of the genetic material. Amniocentesis is a medical procedure to collect amniotic fluid for prenatal genetic testing and is not related to DNA duplication. Meiosis is a type of cell division that produces gametes with half the genetic material of the parent cell, leading to genetic diversity. Mutation is a permanent alteration in the DNA sequence that can lead to genetic variations but is not the process of DNA duplication.
4. A client presents to the office with complaints of swelling in the legs, chills, and shortness of breath. During auscultation of the chest, a heart murmur is heard. The client's blood culture reveals a microorganism in the blood. When a microorganism is found in the blood, this condition is called
- A. Bacteremia
- B. Sepsis
- C. Septicemia
- D. Parasitic infection
Correct answer: A
Rationale: When a microorganism is found in the blood, this condition is called bacteremia, which refers to the presence of bacteria in the bloodstream, as indicated by a positive blood culture. If not appropriately treated, bacteremia can progress to septicemia, also known as sepsis. Sepsis is a severe and life-threatening response to an infection, characterized by systemic inflammation and organ dysfunction. Parasitic infections involve pathogens other than bacteria and are not directly related to the scenario described.
5. During a Weber test, what is an appropriate action for the nurse to take?
- A. Deliver a series of high-pitched sounds at random intervals.
- B. Place an activated tuning fork in the middle of the client's forehead.
- C. Hold an activated tuning fork against the client's mastoid process.
- D. Whisper a series of words softly into one ear.
Correct answer: B
Rationale: During a Weber test, the nurse should place an activated tuning fork in the middle of the client's forehead. This test is used to assess for lateralization of sound in a client with possible hearing issues. Choice A is incorrect because the Weber test does not involve delivering high-pitched sounds at random intervals. Choice C is incorrect as it describes the Rinne test, not the Weber test. Choice D is incorrect as whispering words into one ear is not part of the Weber test procedure.
