HESI Fundamentals Study Guide
1. During an assessment, a nurse is evaluating the breath sounds of an adult client diagnosed with pneumonia. Which of the following actions should the nurse take?
- A. Follow a systematic pattern from side-to-side moving down the client’s chest.
- B. Ask the client to breathe in deeply through their nose.
- C. Instruct the client to sit upright with their head slightly tilted backward.
- D. Place the diaphragm of the stethoscope on the client’s chest.
Correct answer: A
Rationale: When assessing breath sounds in a client with pneumonia, the nurse should follow a systematic pattern from side-to-side moving down the client’s chest. This approach ensures a comprehensive evaluation of breath sounds across different lung fields. Asking the client to breathe in deeply through their nose (Choice B) is not necessary for assessing breath sounds. Instructing the client to sit upright with their head slightly tilted backward (Choice C) is not directly related to assessing breath sounds and may not be required. Placing the diaphragm of the stethoscope on the client’s chest (Choice D) is not the correct technique for auscultating breath sounds, as the diaphragm should be used for this purpose.
2. A healthcare professional is planning to collect a liquid stool specimen from a client for ova and parasites. Inaccurate test results may result if the healthcare professional:
- A. Refrigerates the collected specimen
- B. Collects the specimen in a sterile container
- C. Delays the collection of the specimen
- D. Uses a non-contaminated collection container
Correct answer: A
Rationale: Refrigeration can kill the ova and parasites present in the stool specimen, leading to inaccurate test results. Storing the specimen in a cold environment can disrupt the integrity of the parasites and ova, affecting the accuracy of the test. Collecting the specimen in a sterile container (Choice B) is the correct procedure to prevent external contamination. Delaying the collection of the specimen (Choice C) may affect the freshness of the sample but does not directly impact the test results. Using a non-contaminated collection container (Choice D) is essential to maintain the sample's integrity but does not relate to the risk of killing ova and parasites through refrigeration.
3. A group of students is reviewing information about the various types of insulin used to treat type 1 diabetes. The students demonstrate understanding of the information when they identify which of these insulins as having the longest duration?
- A. Lispro
- B. Regular
- C. NPH
- D. Glargine
Correct answer: D
Rationale: The correct answer is Glargine (Lantus) as it has the longest duration of action among the insulins listed, lasting 12 to 24 hours. Lispro (A) and Regular (B) are rapid-acting insulins with shorter durations of action. NPH (C) is an intermediate-acting insulin with a duration of action of about 12-16 hours. Therefore, Glargine is the correct choice for the insulin with the longest duration.
4. An older adult client just diagnosed with colon cancer asks the nurse what the primary care provider is going to do. The provider will be making rounds within the hour. Which of the following nursing actions is appropriate?
- A. Help the client write down the questions to ask the provider, so that the client doesn’t forget
- B. Reassure the client that everything will be explained
- C. Explain the procedure in detail yourself
- D. Direct the client to search for information online
Correct answer: A
Rationale: Assisting the client in preparing questions is the most appropriate action as it helps ensure that all concerns are addressed during the provider's visit. By helping the client write down questions, the nurse empowers the client to actively participate in their care and communicate effectively with the provider. Reassuring the client, while well-intentioned, may not address the specific questions or fears the client has. Explaining the procedure in detail may not be what the client is seeking at this moment, as their primary concern is about the provider's actions. Directing the client to search for information online is not recommended as it may lead to confusion or misinformation, and the information may not be tailored to the client's specific situation.
5. _____ are environmental agents that can harm the embryo or fetus.
- A. Mutations
- B. Autosomes
- C. Teratogens
- D. Androgens
Correct answer: C
Rationale: Teratogens are environmental agents, such as drugs, chemicals, or infections, that can cause harm to a developing embryo or fetus. Mutations (Choice A) refer to changes in the DNA sequence and are not environmental agents. Autosomes (Choice B) are chromosomes that are not involved in determining an individual's sex and are not environmental agents that harm the embryo or fetus. Androgens (Choice D) are a group of hormones that are more related to male sexual development and function, not environmental agents that harm the embryo or fetus.
