Question 1
Regular
Your patient has been prescribed timolol maleate (Timoptic) eyedrops. Where should you instill the eyedrops?
Correct!
Incorrect
The correct answer is: D
Rationale
D: The lower conjunctival sac. Instilling timolol maleate eyedrops in the lower conjunctival sac ensures optimal absorption and effectiveness of the medication while minimizing discomfort and potential spillage.
A: The cornea. Direct application to the cornea could cause irritation or damage, making it an unsuitable site for eyedrop administration.
B: The pupil. Instilling drops directly onto the pupil does not facilitate proper delivery of the medication, as it may not penetrate effectively.
C: The eyelid. Applying drops to the eyelid would likely lead to insufficient dosage reaching the eye, reducing the medication's therapeutic effect.

Question 2
Multiple Choice
Which of the following techniques is(are) correct when inserting a rectal suppository?
Correct!
Incorrect
The correct answer is: C,D
Rationale
C: Lubricate the tip of the suppository. Proper lubrication reduces friction during insertion, enhancing comfort for the patient and ensuring that the suppository is inserted smoothly and effectively into the rectal cavity.
A: Position the patient on his or her right side with the left leg flexed. While positioning can aid in comfort, it is not a critical technique for effective suppository insertion.
B: During insertion, tell the patient to hold his or her breath. Holding the breath may create tension, which can hinder the process; relaxed breathing is more beneficial for comfort.
D: Gently insert the suppository, directing it with the index finger. This technique is vital for ensuring proper placement and minimizing discomfort during the insertion process, making it a correct method.

Question 3
Multiple Choice
A patient has been prescribed an MDI for the management of her asthma. Which of the following instructions should be given to the patient?
Correct!
Incorrect
The correct answer is: A,B,C,D
Rationale
Shake the inhaler before use. Properly shaking the inhaler ensures that the medication is well-mixed, which is crucial for delivering the correct dose and achieving optimal therapeutic effects for asthma management.
B: Breathe slowly and fully before administration. This instruction is misleading; the patient should exhale fully rather than breathe slowly to prepare for inhalation.
C: Administer by pressing the canister downward. While this action is part of using an inhaler, it lacks specificity regarding the need for coordination with inhalation.
D: Hold your breath as long as possible. Holding the breath for an excessive duration can lead to discomfort and is unnecessary; a brief hold is usually sufficient for effective medication absorption.

Question 4
Regular
Buccal tablets are administered:
Correct!
Incorrect
The correct answer is: B
Rationale
Buccal tablets are administered between the upper lip and gum. This method allows the medication to dissolve and absorb directly into the bloodstream through the buccal mucosa, providing rapid onset of action.
A: under the tongue. Sublingual administration involves placing the drug beneath the tongue, which is different from the buccal route that targets the upper gum area.
C: by injection. Injection methods involve delivering medication directly into the body using a needle, which does not apply to the buccal tablet administration technique.
D: through inhalation. Inhalation refers to delivering medication via the respiratory system, contrasting with buccal tablets that are intended for oral mucosal absorption, not respiratory delivery.

Question 5
Multiple Choice
What steps should the nurse follow when administering a liquid cough syrup to a patient?
Correct!
Incorrect
The correct answer is: A,B,C
Rationale
Holding the medicine glass at eye level and pouring the prescribed dose ensures accurate measurement and proper administration of the liquid cough syrup, promoting patient safety and effective treatment.
B: The measurement line should be even with the fluid level at the base of the meniscus ensures precision but does not encompass the initial action of pouring the syrup.
C: Discard any excess may be necessary after measuring, but it does not highlight the critical first step of correctly pouring the syrup.
D: Dilute all liquids with water is not applicable for cough syrup administration, as it could alter the medication's effectiveness and concentration.

Question 6
Regular
Which of the following drug administration routes is the safest and most convenient?
Correct!
Incorrect
The correct answer is: A
Rationale
Oral. This route is considered the safest and most convenient due to ease of administration, patient compliance, and the ability to self-administer without the need for medical assistance, making it widely preferred.
B: Topical. While topical administration is straightforward, it may not provide systemic effects and can lead to varying absorption rates based on skin condition and application technique.
C: Vaginal. Vaginal administration can be effective for localized treatment but may lack convenience for patients and is often less socially acceptable, limiting its widespread use.
D: Nasal. Nasal administration can be effective for rapid absorption but may cause discomfort and irritation, making it less favorable compared to the simplicity of oral methods.

Question 7
Regular
Which of the following drug administration routes is through the epidermal layer of skin into the dermis?
Correct!
Incorrect
The correct answer is: B
Rationale
Topical administration is through the epidermal layer of skin into the dermis. This method allows for localized treatment as it delivers medication directly to the target area, ensuring effective absorption and minimizing systemic side effects.
A: Oral Administration involves ingesting drugs, which travel through the digestive system rather than penetrating the skin layers. Thus, it does not deliver substances through the epidermis or dermis.
C: Inhalation delivers medication directly to the lungs via the respiratory tract, bypassing the skin entirely. This method targets respiratory conditions rather than utilizing dermal absorption.
D: Intravenous administration involves injecting drugs directly into the bloodstream. This method completely circumvents the skin layers and focuses on immediate systemic effects rather than localized dermal delivery.

Question 8
Regular
Which of the following drug administration routes is rapid and across a large surface area?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Inhalation provides a rapid onset of action due to the large surface area of the lungs, allowing medications to quickly enter the bloodstream and achieve therapeutic effects almost immediately.
A: Oral administration involves digestion and absorption through the gastrointestinal tract, which is slower and less efficient compared to inhalation's direct entry into the bloodstream.
B: Topical application primarily delivers drugs to localized areas, limiting systemic absorption and resulting in a slower onset than inhalation, which targets the lungs directly.
D: Rectal administration can be effective but typically does not offer the same rapid absorption and extensive surface area for distribution as the inhalation route provides.

Question 9
Regular
After administering medication in the enteral tube, how much water do you Servicing use to clear the tube?
Correct!
Incorrect
The correct answer is: A
Rationale
To clear the enteral tube after administering medication, 20 to 30 ml of water should be used. This volume effectively ensures that the medication is properly flushed through the tube, minimizing residual buildup.
B: 25 to 35 ml. This range exceeds the recommended amount, which may lead to excessive fluid intake or complications for the patient, making it unsuitable for tube clearance.
C: 5 to 15 ml. This volume is insufficient to adequately clear the tube, potentially leaving medication residue that could affect subsequent doses or patient safety.
D: 30 to 60 ml. This larger volume may pose a risk of overhydration and discomfort for the patient, making it impractical for effective tube clearing after medication administration.
