Samuel, a 65-year-old patient comes into the hospital for an anginal attack. Which of the following is an important nursing intervention when administering Nitroglycerine?

Correct Answer: C

Rationale: The correct nursing intervention when administering Nitroglycerine to a patient like Samuel is to remove the transdermal patch 10-12 hours every night to prevent tolerance. Tolerance can develop rapidly with Nitroglycerine, leading to decreased effectiveness in managing anginal attacks. By removing the patch at night, the body has a chance to "reset" and reduce the likelihood of tolerance development. This practice helps maintain the drug's effectiveness and ensures better symptom control for the patient.

Correct Answer: D

Rationale: Pain relief in pregnancy avoids fetal harm. Ketorolac , an NSAID, risks ductal closure, disrupting fetal circulation. Acetaminophen , Codeine , Hydrocodone , and Morphine (E) are safer. Ketorolac's prostaglandin inhibition contraindicates it late in gestation.

Correct Answer: B

Rationale: Before administering a potassium supplement to a patient, it is crucial to check the patient's serum potassium level. This is because if the serum potassium level is already elevated or within the high end of the normal range, giving additional potassium could lead to hyperkalemia, which can be life-threatening. Conversely, if the serum potassium level is low (hypokalemia), then administering potassium supplementation may be necessary to correct the deficiency. Monitoring the serum potassium level helps ensure safe and effective treatment with potassium supplements. It is a critical part of assessing the patient's electrolyte balance and overall health status.

Correct Answer: B

Rationale: Bromocriptine, a dopamine D2 agonist used in Parkinson's, has ergot alkaloid properties, which can cause vasospasm by stimulating vascular smooth muscle receptors, occasionally leading to Raynaud's-like symptoms or digital ischemia. Amantadine, an NMDA antagonist, enhances dopamine release but lacks vasoconstrictive effects. Carbidopa inhibits dopa decarboxylase, aiding levodopa delivery without vascular impact. Entacapone, a COMT inhibitor, extends levodopa's duration but doesn't affect vessels. Ropinirole, a non-ergot agonist, avoids vasospasm. Bromocriptine's ergot-derived vasoconstriction, though rare, distinguishes it among antiparkinsonian drugs, requiring caution in patients with vascular risks.

Correct Answer: B

Rationale: Succinylcholine is a trigger for malignant hyperthermia in susceptible individuals due to its effects on calcium release in muscle cells.
