Nokea
A solution for the eyes
- A. effervescent
- B. mucilage
- C. spirits
- D. collyria
Correct Answer: D
Rationale: Collyria refers to eye drops or an eye lotion that is used to treat eye conditions. When the question is asking for a solution for the eyes, collyria is the most appropriate choice among the options given. Effervescent, mucilage, and spirits do not specifically relate to eye treatments. Collodion is a type of liquid adhesive used in medical settings, but it is not primarily intended for eye-related issues. Therefore, collyria is the correct solution for the eyes.

A healthcare professional is preparing to administer verapamil by IV bolus to a client who is experiencing cardiac dysrhythmias. For which of the following adverse effects should the healthcare professional monitor when giving this medication?
- A. Hyperthermia
- B. Hypotension
- C. Ototoxicity
- D. Muscle pain
Correct Answer: B
Rationale: Verapamil is known to cause hypotension as one of its adverse effects due to its vasodilatory properties. Therefore, it is essential for the healthcare professional to monitor the client's blood pressure closely during and after administration to prevent complications such as severe hypotension. Hyperthermia, ototoxicity, and muscle pain are not commonly associated with verapamil administration, making choices A, C, and D incorrect.
A client has a new prescription for Atenolol. Which of the following client statements indicates an understanding of the teaching?
- A. I should monitor my blood pressure regularly.
- B. I will take this medication at bedtime.
- C. I will take this medication with a high-fat meal.
- D. I should increase my intake of potassium-rich foods.
Correct Answer: A
Rationale: The correct answer is A. Clients taking Atenolol, a beta-blocker, should monitor their blood pressure regularly to ensure the medication is effectively managing their condition. Monitoring blood pressure helps in assessing the drug's effectiveness and identifying any potential side effects that may influence blood pressure levels. Choices B, C, and D are incorrect because taking Atenolol at bedtime, with a high-fat meal, or increasing potassium-rich foods intake are not recommended actions associated with this medication and do not demonstrate an understanding of the teaching.
Which of the following should the nurse include when providing dietary teaching for the patient receiving warfarin (Coumadin) therapy?
- A. Avoid drinking large amounts of green te
- C. Cranberry juice will provide you with needed nutrients while taking Coumadin.
- D. You must never eat spinach.
Correct Answer: A
Rationale: The nurse should include the instruction to avoid drinking large amounts of green tea when providing dietary teaching for a patient receiving warfarin (Coumadin) therapy because green tea contains vitamin K, which can interfere with the anticoagulant effects of warfarin. Maintaining consistent intake of vitamin K is important to ensure the effectiveness of warfarin therapy. Therefore, it is recommended for patients on warfarin to consume a consistent amount of vitamin K-containing foods and avoid sudden, significant changes in their intake.
The nurse is caring for a client receiving tamoxifen (Nolvadex) for breast cancer. Which side effect should the nurse monitor for?
- A. Hot flashes
- B. Hair loss
- C. Nausea
- D. Diarrhea
Correct Answer: A
Rationale: Tamoxifen, an estrogen receptor modulator, treats breast cancer but blocks estrogen in some tissues, causing hot flashes , a common menopausal-like effect. Monitoring this ensures client comfort and adherence, as it's frequent and distressing. Hair loss is more chemotherapy-related, not tamoxifen. Nausea and diarrhea occur less often and are less specific. Hot flashes align with tamoxifen's anti-estrogenic action, a key consideration in breast cancer management where long-term use is common. This focus aids in symptom management, distinguishing it from cytotoxic effects, making A the priority side effect to monitor.
The following are true for adrenaline EXCEPT:
- A. it acts via G-proteins
- B. alpha receptor stimulation results in decreased cAMP production
- C. it may be administered via inhalation, orally and parentally
- D. it has no active metabolites
Correct Answer: C
Rationale: Adrenaline, or epinephrine, is a catecholamine that exerts its effects through adrenergic receptors, which are G-protein-coupled, making its action via G-proteins a true statement. Alpha receptor stimulation typically inhibits adenylate cyclase, reducing cyclic AMP (cAMP) production, which aligns with its known pharmacology and is also true. Adrenaline can indeed be administered via inhalation (e.g., for asthma), orally (though less common), and parenterally (e.g., intramuscularly in anaphylaxis), confirming this as true. However, adrenaline does have active metabolites, such as metanephrine and normetanephrine, produced via catechol-O-methyltransferase (COMT) metabolism, making the statement about having no active metabolites false. In cardiac arrest, it facilitates CPR by causing peripheral vasoconstriction, increasing coronary perfusion pressure, which is true. The false statement here is about the absence of active metabolites, as adrenaline's breakdown products retain some activity, a key point in understanding its pharmacokinetics and duration of effect.
