Nursing Elites

1. What can cause a low pulse oximetry reading?

• A. Hyperthermia
• B. Increased hemoglobin level
• C. Inadequate peripheral circulation
• D. Low altitudes

Correct answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.

2. A nurse is caring for a client who has dehydration. The client has a peripheral IV and has a prescription for an infusion of 0.9% sodium chloride 1,000 mL with 40 mEq potassium chloride to infuse over 1 hr. Which of the following actions should the nurse take first?

• A. Teach the client to report findings of IV extravasation
• B. Evaluate the patency of the IV
• C. Consult with the pharmacist about the prescription
• D. Verify the prescription with the provider

Correct answer: D

Rationale: The priority action is to verify the prescription with the provider. Verifying the prescription ensures patient safety by preventing fluid volume overload and dysrhythmias, which can result from infusing potassium too rapidly. Teaching the client about IV extravasation, evaluating IV patency, and consulting with the pharmacist are important but should come after verifying the prescription to ensure the ordered treatment is appropriate and safe for the client's condition.

3. A nurse is providing teaching to a client who has mild persistent asthma and has been prescribed montelukast. Which of the following statements should the nurse include in the teaching?

• A. This medication can be used to help manage asthma symptoms during an acute asthma attack
• B. This medication should be taken before exercise and physical activity
• C. This medication should be taken regularly as prescribed without discontinuing abruptly
• D. This medication helps decrease swelling and mucus production

Correct answer: D

Rationale: Montelukast works as a leukotriene receptor antagonist, reducing inflammation and mucus production, which helps prevent asthma attacks but is not used for acute treatment. It is important for the client to understand that montelukast should be taken regularly to manage asthma symptoms and should not be abruptly discontinued. Taking the medication before exercise is not a typical instruction for montelukast.

4. A nurse is discussing immunity with a client who has received an immunization. The nurse should identify that an immunization functions as part of which of the following types of immunity?

• A. Innate immunity
• B. Passive immunity
• C. Acquired immunity
• D. Natural immunity

Correct answer: C

Rationale: Immunizations provide acquired immunity. They work by introducing antigens into the body, which triggers the immune system to produce antibodies specific to that antigen. Choice A, 'Innate immunity,' refers to the natural defense mechanisms an organism is born with and does not involve immunizations. Choice B, 'Passive immunity,' is the transfer of pre-formed antibodies and does not involve immunizations. Choice D, 'Natural immunity,' is a general term that encompasses all immunity that is not acquired through deliberate immunization or passive transfer of antibodies.

5. A nurse is conducting an infertility assessment for a newly admitted client. Which of the following factors should the nurse identify as affecting the client's fertility?

• A. Premature ovarian failure
• B. Renal calculi
• C. Dysmenorrhea
• D. Recurrent urinary tract infection

Correct answer: A

Rationale: Premature ovarian failure should be identified as affecting the client's fertility. It leads to reduced or absent ovarian function, resulting in decreased estrogen production and irregular menstrual cycles, which can impact fertility. Renal calculi, dysmenorrhea, and recurrent urinary tract infections do not directly affect fertility and are not typically associated with infertility assessments. Renal calculi are kidney stones that do not directly relate to reproductive health. Dysmenorrhea is painful menstruation but does not necessarily indicate infertility. Recurrent urinary tract infections primarily affect the urinary system and do not directly impact fertility.
